Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473078, here are decompositions:

17 + 2147473061 = 2147473078
29 + 2147473049 = 2147473078
281 + 2147472797 = 2147473078
389 + 2147472689 = 2147473078
419 + 2147472659 = 2147473078
461 + 2147472617 = 2147473078
467 + 2147472611 = 2147473078
521 + 2147472557 = 2147473078

Showing the first eight; more decompositions exist.
