Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978378, here are decompositions:

17 + 4294978361 = 4294978378
71 + 4294978307 = 4294978378
167 + 4294978211 = 4294978378
311 + 4294978067 = 4294978378
389 + 4294977989 = 4294978378
479 + 4294977899 = 4294978378
617 + 4294977761 = 4294978378
947 + 4294977431 = 4294978378

Showing the first eight; more decompositions exist.
