Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489774, here are decompositions:

61 + 2147489713 = 2147489774
271 + 2147489503 = 2147489774
337 + 2147489437 = 2147489774
373 + 2147489401 = 2147489774
571 + 2147489203 = 2147489774
631 + 2147489143 = 2147489774
691 + 2147489083 = 2147489774
751 + 2147489023 = 2147489774

Showing the first eight; more decompositions exist.
