Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967942, here are decompositions:

151 + 4294967791 = 4294967942
163 + 4294967779 = 4294967942
241 + 4294967701 = 4294967942
373 + 4294967569 = 4294967942
379 + 4294967563 = 4294967942
571 + 4294967371 = 4294967942
631 + 4294967311 = 4294967942
1033 + 4294966909 = 4294967942

Showing the first eight; more decompositions exist.
