Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490854, here are decompositions:

43 + 2147490811 = 2147490854
127 + 2147490727 = 2147490854
277 + 2147490577 = 2147490854
367 + 2147490487 = 2147490854
571 + 2147490283 = 2147490854
907 + 2147489947 = 2147490854
937 + 2147489917 = 2147490854
1033 + 2147489821 = 2147490854

Showing the first eight; more decompositions exist.
