Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490806, here are decompositions:

7 + 2147490799 = 2147490806
37 + 2147490769 = 2147490806
67 + 2147490739 = 2147490806
79 + 2147490727 = 2147490806
229 + 2147490577 = 2147490806
277 + 2147490529 = 2147490806
463 + 2147490343 = 2147490806
523 + 2147490283 = 2147490806

Showing the first eight; more decompositions exist.
