Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501938, here are decompositions:

269 + 2147501669 = 2147501938
311 + 2147501627 = 2147501938
419 + 2147501519 = 2147501938
761 + 2147501177 = 2147501938
809 + 2147501129 = 2147501938
929 + 2147501009 = 2147501938
1031 + 2147500907 = 2147501938
1049 + 2147500889 = 2147501938

Showing the first eight; more decompositions exist.
