Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294996978, here are decompositions:

17 + 4294996961 = 4294996978
269 + 4294996709 = 4294996978
659 + 4294996319 = 4294996978
929 + 4294996049 = 4294996978
971 + 4294996007 = 4294996978
1061 + 4294995917 = 4294996978
1277 + 4294995701 = 4294996978
1319 + 4294995659 = 4294996978

Showing the first eight; more decompositions exist.
