Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492986, here are decompositions:

47 + 2147492939 = 2147492986
227 + 2147492759 = 2147492986
347 + 2147492639 = 2147492986
389 + 2147492597 = 2147492986
557 + 2147492429 = 2147492986
593 + 2147492393 = 2147492986
599 + 2147492387 = 2147492986
647 + 2147492339 = 2147492986

Showing the first eight; more decompositions exist.
