Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294992778, here are decompositions:

29 + 4294992749 = 4294992778
101 + 4294992677 = 4294992778
311 + 4294992467 = 4294992778
467 + 4294992311 = 4294992778
701 + 4294992077 = 4294992778
887 + 4294991891 = 4294992778
929 + 4294991849 = 4294992778
941 + 4294991837 = 4294992778

Showing the first eight; more decompositions exist.
