Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967978, here are decompositions:

157 + 4294967821 = 4294967978
181 + 4294967797 = 4294967978
199 + 4294967779 = 4294967978
277 + 4294967701 = 4294967978
409 + 4294967569 = 4294967978
439 + 4294967539 = 4294967978
601 + 4294967377 = 4294967978
607 + 4294967371 = 4294967978

Showing the first eight; more decompositions exist.
