Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486380, here are decompositions:

41 + 2147486339 = 2147486380
59 + 2147486321 = 2147486380
131 + 2147486249 = 2147486380
233 + 2147486147 = 2147486380
251 + 2147486129 = 2147486380
269 + 2147486111 = 2147486380
359 + 2147486021 = 2147486380
467 + 2147485913 = 2147486380

Showing the first eight; more decompositions exist.
