Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978678, here are decompositions:

17 + 4294978661 = 4294978678
167 + 4294978511 = 4294978678
317 + 4294978361 = 4294978678
467 + 4294978211 = 4294978678
509 + 4294978169 = 4294978678
521 + 4294978157 = 4294978678
587 + 4294978091 = 4294978678
797 + 4294977881 = 4294978678

Showing the first eight; more decompositions exist.
