Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987778, here are decompositions:

7 + 4294987771 = 4294987778
97 + 4294987681 = 4294987778
127 + 4294987651 = 4294987778
157 + 4294987621 = 4294987778
199 + 4294987579 = 4294987778
421 + 4294987357 = 4294987778
547 + 4294987231 = 4294987778
727 + 4294987051 = 4294987778

Showing the first eight; more decompositions exist.
