Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490942, here are decompositions:

19 + 2147490923 = 2147490942
43 + 2147490899 = 2147490942
59 + 2147490883 = 2147490942
71 + 2147490871 = 2147490942
109 + 2147490833 = 2147490942
131 + 2147490811 = 2147490942
173 + 2147490769 = 2147490942
211 + 2147490731 = 2147490942

Showing the first eight; more decompositions exist.
