Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486940, here are decompositions:

13 + 2147486927 = 2147486940
31 + 2147486909 = 2147486940
61 + 2147486879 = 2147486940
83 + 2147486857 = 2147486940
89 + 2147486851 = 2147486940
97 + 2147486843 = 2147486940
113 + 2147486827 = 2147486940
149 + 2147486791 = 2147486940

Showing the first eight; more decompositions exist.

IPv4 address
