Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490438, here are decompositions:

199 + 2147490239 = 2147490438
277 + 2147490161 = 2147490438
349 + 2147490089 = 2147490438
491 + 2147489947 = 2147490438
521 + 2147489917 = 2147490438
617 + 2147489821 = 2147490438
619 + 2147489819 = 2147490438
641 + 2147489797 = 2147490438

Showing the first eight; more decompositions exist.
