Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467918, here are decompositions:

47 + 2147467871 = 2147467918
149 + 2147467769 = 2147467918
251 + 2147467667 = 2147467918
359 + 2147467559 = 2147467918
587 + 2147467331 = 2147467918
797 + 2147467121 = 2147467918
971 + 2147466947 = 2147467918
1049 + 2147466869 = 2147467918

Showing the first eight; more decompositions exist.
