Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978738, here are decompositions:

5 + 4294978733 = 4294978738
59 + 4294978679 = 4294978738
179 + 4294978559 = 4294978738
227 + 4294978511 = 4294978738
431 + 4294978307 = 4294978738
569 + 4294978169 = 4294978738
647 + 4294978091 = 4294978738
839 + 4294977899 = 4294978738

Showing the first eight; more decompositions exist.
