Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490578, here are decompositions:

127 + 2147490451 = 2147490578
349 + 2147490229 = 2147490578
631 + 2147489947 = 2147490578
661 + 2147489917 = 2147490578
757 + 2147489821 = 2147490578
991 + 2147489587 = 2147490578
1231 + 2147489347 = 2147490578
1279 + 2147489299 = 2147490578

Showing the first eight; more decompositions exist.
