Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490690, here are decompositions:

31 + 2147490659 = 2147490690
97 + 2147490593 = 2147490690
101 + 2147490589 = 2147490690
109 + 2147490581 = 2147490690
113 + 2147490577 = 2147490690
151 + 2147490539 = 2147490690
227 + 2147490463 = 2147490690
239 + 2147490451 = 2147490690

Showing the first eight; more decompositions exist.
