Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294991288, here are decompositions:

37 + 4294991251 = 4294991288
109 + 4294991179 = 4294991288
127 + 4294991161 = 4294991288
139 + 4294991149 = 4294991288
277 + 4294991011 = 4294991288
607 + 4294990681 = 4294991288
631 + 4294990657 = 4294991288
691 + 4294990597 = 4294991288

Showing the first eight; more decompositions exist.
