Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492278, here are decompositions:

17 + 2147492261 = 2147492278
47 + 2147492231 = 2147492278
317 + 2147491961 = 2147492278
521 + 2147491757 = 2147492278
587 + 2147491691 = 2147492278
719 + 2147491559 = 2147492278
761 + 2147491517 = 2147492278
929 + 2147491349 = 2147492278

Showing the first eight; more decompositions exist.
