Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486790, here are decompositions:

41 + 2147486749 = 2147486790
79 + 2147486711 = 2147486790
83 + 2147486707 = 2147486790
101 + 2147486689 = 2147486790
149 + 2147486641 = 2147486790
173 + 2147486617 = 2147486790
191 + 2147486599 = 2147486790
233 + 2147486557 = 2147486790

Showing the first eight; more decompositions exist.

IPv4 address
