Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490874, here are decompositions:

3 + 2147490871 = 2147490874
41 + 2147490833 = 2147490874
101 + 2147490773 = 2147490874
281 + 2147490593 = 2147490874
293 + 2147490581 = 2147490874
317 + 2147490557 = 2147490874
461 + 2147490413 = 2147490874
797 + 2147490077 = 2147490874

Showing the first eight; more decompositions exist.
