Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486748, here are decompositions:

7 + 2147486741 = 2147486748
37 + 2147486711 = 2147486748
41 + 2147486707 = 2147486748
59 + 2147486689 = 2147486748
79 + 2147486669 = 2147486748
107 + 2147486641 = 2147486748
131 + 2147486617 = 2147486748
149 + 2147486599 = 2147486748

Showing the first eight; more decompositions exist.

IPv4 address
