Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486494, here are decompositions:

71 + 2147486423 = 2147486494
107 + 2147486387 = 2147486494
173 + 2147486321 = 2147486494
347 + 2147486147 = 2147486494
383 + 2147486111 = 2147486494
617 + 2147485877 = 2147486494
653 + 2147485841 = 2147486494
677 + 2147485817 = 2147486494

Showing the first eight; more decompositions exist.
