Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978686, here are decompositions:

7 + 4294978679 = 4294978686
59 + 4294978627 = 4294978686
127 + 4294978559 = 4294978686
197 + 4294978489 = 4294978686
353 + 4294978333 = 4294978686
359 + 4294978327 = 4294978686
373 + 4294978313 = 4294978686
379 + 4294978307 = 4294978686

Showing the first eight; more decompositions exist.
