Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489782, here are decompositions:

83 + 2147489699 = 2147489782
131 + 2147489651 = 2147489782
239 + 2147489543 = 2147489782
359 + 2147489423 = 2147489782
491 + 2147489291 = 2147489782
863 + 2147488919 = 2147489782
1031 + 2147488751 = 2147489782
1091 + 2147488691 = 2147489782

Showing the first eight; more decompositions exist.

IPv4 address
