Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491996, here are decompositions:

59 + 2147491937 = 2147491996
239 + 2147491757 = 2147491996
263 + 2147491733 = 2147491996
389 + 2147491607 = 2147491996
443 + 2147491553 = 2147491996
449 + 2147491547 = 2147491996
479 + 2147491517 = 2147491996
593 + 2147491403 = 2147491996

Showing the first eight; more decompositions exist.

IPv4 address
