Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487158, here are decompositions:

109 + 2147487049 = 2147487158
307 + 2147486851 = 2147487158
331 + 2147486827 = 2147487158
367 + 2147486791 = 2147487158
409 + 2147486749 = 2147487158
541 + 2147486617 = 2147487158
571 + 2147486587 = 2147487158
601 + 2147486557 = 2147487158

Showing the first eight; more decompositions exist.

IPv4 address
