Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472718, here are decompositions:

5 + 2147472713 = 2147472718
29 + 2147472689 = 2147472718
59 + 2147472659 = 2147472718
101 + 2147472617 = 2147472718
107 + 2147472611 = 2147472718
227 + 2147472491 = 2147472718
269 + 2147472449 = 2147472718
467 + 2147472251 = 2147472718

Showing the first eight; more decompositions exist.
