Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294992988, here are decompositions:

17 + 4294992971 = 4294992988
47 + 4294992941 = 4294992988
89 + 4294992899 = 4294992988
191 + 4294992797 = 4294992988
239 + 4294992749 = 4294992988
311 + 4294992677 = 4294992988
521 + 4294992467 = 4294992988
647 + 4294992341 = 4294992988

Showing the first eight; more decompositions exist.
