Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295039778, here are decompositions:

137 + 4295039641 = 4295039778
151 + 4295039627 = 4295039778
167 + 4295039611 = 4295039778
241 + 4295039537 = 4295039778
311 + 4295039467 = 4295039778
347 + 4295039431 = 4295039778
397 + 4295039381 = 4295039778
401 + 4295039377 = 4295039778

Showing the first eight; more decompositions exist.
