Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492770, here are decompositions:

11 + 2147492759 = 2147492770
29 + 2147492741 = 2147492770
131 + 2147492639 = 2147492770
149 + 2147492621 = 2147492770
173 + 2147492597 = 2147492770
179 + 2147492591 = 2147492770
281 + 2147492489 = 2147492770
383 + 2147492387 = 2147492770

Showing the first eight; more decompositions exist.
