Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492990, here are decompositions:

31 + 2147492959 = 2147492990
61 + 2147492929 = 2147492990
67 + 2147492923 = 2147492990
337 + 2147492653 = 2147492990
439 + 2147492551 = 2147492990
457 + 2147492533 = 2147492990
463 + 2147492527 = 2147492990
499 + 2147492491 = 2147492990

Showing the first eight; more decompositions exist.

IPv4 address
