Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487290, here are decompositions:

31 + 2147487259 = 2147487290
43 + 2147487247 = 2147487290
103 + 2147487187 = 2147487290
241 + 2147487049 = 2147487290
433 + 2147486857 = 2147487290
439 + 2147486851 = 2147487290
463 + 2147486827 = 2147487290
499 + 2147486791 = 2147487290

Showing the first eight; more decompositions exist.

IPv4 address
