Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294992638, here are decompositions:

199 + 4294992439 = 4294992638
397 + 4294992241 = 4294992638
487 + 4294992151 = 4294992638
499 + 4294992139 = 4294992638
619 + 4294992019 = 4294992638
631 + 4294992007 = 4294992638
661 + 4294991977 = 4294992638
751 + 4294991887 = 4294992638

Showing the first eight; more decompositions exist.
