Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967440, here are decompositions:

53 + 4294967387 = 4294967440
83 + 4294967357 = 4294967440
149 + 4294967291 = 4294967440
251 + 4294967189 = 4294967440
353 + 4294967087 = 4294967440
443 + 4294966997 = 4294967440
563 + 4294966877 = 4294967440
773 + 4294966667 = 4294967440

Showing the first eight; more decompositions exist.
