Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484788, here are decompositions:

37 + 2147484751 = 2147484788
67 + 2147484721 = 2147484788
109 + 2147484679 = 2147484788
271 + 2147484517 = 2147484788
349 + 2147484439 = 2147484788
439 + 2147484349 = 2147484788
457 + 2147484331 = 2147484788
727 + 2147484061 = 2147484788

Showing the first eight; more decompositions exist.
