Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487272, here are decompositions:

3 + 2147487269 = 2147487272
13 + 2147487259 = 2147487272
103 + 2147487169 = 2147487272
223 + 2147487049 = 2147487272
421 + 2147486851 = 2147487272
523 + 2147486749 = 2147487272
631 + 2147486641 = 2147487272
673 + 2147486599 = 2147487272

Showing the first eight; more decompositions exist.

IPv4 address
