Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490798, here are decompositions:

29 + 2147490769 = 2147490798
59 + 2147490739 = 2147490798
67 + 2147490731 = 2147490798
71 + 2147490727 = 2147490798
109 + 2147490689 = 2147490798
139 + 2147490659 = 2147490798
241 + 2147490557 = 2147490798
269 + 2147490529 = 2147490798

Showing the first eight; more decompositions exist.
