Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978000, here are decompositions:

11 + 4294977989 = 4294978000
101 + 4294977899 = 4294978000
107 + 4294977893 = 4294978000
239 + 4294977761 = 4294978000
569 + 4294977431 = 4294978000
587 + 4294977413 = 4294978000
653 + 4294977347 = 4294978000
683 + 4294977317 = 4294978000

Showing the first eight; more decompositions exist.
