Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492778, here are decompositions:

19 + 2147492759 = 2147492778
37 + 2147492741 = 2147492778
107 + 2147492671 = 2147492778
139 + 2147492639 = 2147492778
157 + 2147492621 = 2147492778
181 + 2147492597 = 2147492778
227 + 2147492551 = 2147492778
239 + 2147492539 = 2147492778

Showing the first eight; more decompositions exist.
