Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294979278, here are decompositions:

41 + 4294979237 = 4294979278
71 + 4294979207 = 4294979278
167 + 4294979111 = 4294979278
197 + 4294979081 = 4294979278
269 + 4294979009 = 4294979278
467 + 4294978811 = 4294979278
479 + 4294978799 = 4294979278
521 + 4294978757 = 4294979278

Showing the first eight; more decompositions exist.
