Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493774, here are decompositions:

43 + 2147493731 = 2147493774
61 + 2147493713 = 2147493774
67 + 2147493707 = 2147493774
103 + 2147493671 = 2147493774
113 + 2147493661 = 2147493774
157 + 2147493617 = 2147493774
227 + 2147493547 = 2147493774
317 + 2147493457 = 2147493774

Showing the first eight; more decompositions exist.
