Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490892, here are decompositions:

59 + 2147490833 = 2147490892
233 + 2147490659 = 2147490892
311 + 2147490581 = 2147490892
353 + 2147490539 = 2147490892
479 + 2147490413 = 2147490892
653 + 2147490239 = 2147490892
839 + 2147490053 = 2147490892
881 + 2147490011 = 2147490892

Showing the first eight; more decompositions exist.
