Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486844, here are decompositions:

17 + 2147486827 = 2147486844
53 + 2147486791 = 2147486844
103 + 2147486741 = 2147486844
137 + 2147486707 = 2147486844
227 + 2147486617 = 2147486844
257 + 2147486587 = 2147486844
313 + 2147486531 = 2147486844
317 + 2147486527 = 2147486844

Showing the first eight; more decompositions exist.
