Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978688, here are decompositions:

61 + 4294978627 = 4294978688
97 + 4294978591 = 4294978688
199 + 4294978489 = 4294978688
307 + 4294978381 = 4294978688
379 + 4294978309 = 4294978688
439 + 4294978249 = 4294978688
457 + 4294978231 = 4294978688
487 + 4294978201 = 4294978688

Showing the first eight; more decompositions exist.
