Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147494738, here are decompositions:

5 + 2147494733 = 2147494738
29 + 2147494709 = 2147494738
41 + 2147494697 = 2147494738
167 + 2147494571 = 2147494738
227 + 2147494511 = 2147494738
251 + 2147494487 = 2147494738
269 + 2147494469 = 2147494738
479 + 2147494259 = 2147494738

Showing the first eight; more decompositions exist.
