Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490918, here are decompositions:

19 + 2147490899 = 2147490918
47 + 2147490871 = 2147490918
107 + 2147490811 = 2147490918
149 + 2147490769 = 2147490918
179 + 2147490739 = 2147490918
191 + 2147490727 = 2147490918
229 + 2147490689 = 2147490918
337 + 2147490581 = 2147490918

Showing the first eight; more decompositions exist.
