This software identifies prime numbers located in a digit range; this range can be up to 4 trillion. Two steps to determine these figures: it is first to indicate the number of early beach.
 If nothing is specified, the range starts at zero; can not exceed 4 000 000 000 000, then you have to choose a range of numbers (100, 100 or 10 000); default range is 100 digits then do "Ok research"; the prime numbers in this range are then presented fairly quickly in a drop-down list.
It is possible to reset the number of early range ("Clear") or change the right ("<")
The prime numbers are distributed (apparently) in a random manner and it is possible to find areas of hundreds of consecutive digits, or there is none; Here this small software may submit a thirty billion; if one looks at one per second, it would take about 1,000 years to see them all.
