Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486916, here are decompositions:

7 + 2147486909 = 2147486916
37 + 2147486879 = 2147486916
59 + 2147486857 = 2147486916
67 + 2147486849 = 2147486916
73 + 2147486843 = 2147486916
89 + 2147486827 = 2147486916
97 + 2147486819 = 2147486916
167 + 2147486749 = 2147486916

Showing the first eight; more decompositions exist.

IPv4 address
