Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490460, here are decompositions:

47 + 2147490413 = 2147490460
197 + 2147490263 = 2147490460
383 + 2147490077 = 2147490460
449 + 2147490011 = 2147490460
491 + 2147489969 = 2147490460
503 + 2147489957 = 2147490460
587 + 2147489873 = 2147490460
617 + 2147489843 = 2147490460

Showing the first eight; more decompositions exist.
