Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978578, here are decompositions:

19 + 4294978559 = 4294978578
61 + 4294978517 = 4294978578
67 + 4294978511 = 4294978578
89 + 4294978489 = 4294978578
179 + 4294978399 = 4294978578
197 + 4294978381 = 4294978578
251 + 4294978327 = 4294978578
269 + 4294978309 = 4294978578

Showing the first eight; more decompositions exist.
