Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978816, here are decompositions:

5 + 4294978811 = 4294978816
17 + 4294978799 = 4294978816
59 + 4294978757 = 4294978816
83 + 4294978733 = 4294978816
137 + 4294978679 = 4294978816
257 + 4294978559 = 4294978816
263 + 4294978553 = 4294978816
503 + 4294978313 = 4294978816

Showing the first eight; more decompositions exist.
