Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487666, here are decompositions:

17 + 2147487649 = 2147487666
29 + 2147487637 = 2147487666
43 + 2147487623 = 2147487666
59 + 2147487607 = 2147487666
67 + 2147487599 = 2147487666
157 + 2147487509 = 2147487666
193 + 2147487473 = 2147487666
257 + 2147487409 = 2147487666

Showing the first eight; more decompositions exist.

IPv4 address
