Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492638, here are decompositions:

17 + 2147492621 = 2147492638
29 + 2147492609 = 2147492638
41 + 2147492597 = 2147492638
47 + 2147492591 = 2147492638
149 + 2147492489 = 2147492638
191 + 2147492447 = 2147492638
251 + 2147492387 = 2147492638
311 + 2147492327 = 2147492638

Showing the first eight; more decompositions exist.
