Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486678, here are decompositions:

37 + 2147486641 = 2147486678
61 + 2147486617 = 2147486678
79 + 2147486599 = 2147486678
151 + 2147486527 = 2147486678
349 + 2147486329 = 2147486678
367 + 2147486311 = 2147486678
409 + 2147486269 = 2147486678
661 + 2147486017 = 2147486678

Showing the first eight; more decompositions exist.
