Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487698, here are decompositions:

7 + 2147487691 = 2147487698
61 + 2147487637 = 2147487698
127 + 2147487571 = 2147487698
157 + 2147487541 = 2147487698
397 + 2147487301 = 2147487698
439 + 2147487259 = 2147487698
541 + 2147487157 = 2147487698
907 + 2147486791 = 2147487698

Showing the first eight; more decompositions exist.

IPv4 address
