Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294988978, here are decompositions:

31 + 4294988947 = 4294988978
271 + 4294988707 = 4294988978
337 + 4294988641 = 4294988978
421 + 4294988557 = 4294988978
601 + 4294988377 = 4294988978
751 + 4294988227 = 4294988978
967 + 4294988011 = 4294988978
1129 + 4294987849 = 4294988978

Showing the first eight; more decompositions exist.
