Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492790, here are decompositions:

31 + 2147492759 = 2147492790
89 + 2147492701 = 2147492790
137 + 2147492653 = 2147492790
151 + 2147492639 = 2147492790
181 + 2147492609 = 2147492790
193 + 2147492597 = 2147492790
199 + 2147492591 = 2147492790
239 + 2147492551 = 2147492790

Showing the first eight; more decompositions exist.
