Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501566, here are decompositions:

47 + 2147501519 = 2147501566
263 + 2147501303 = 2147501566
293 + 2147501273 = 2147501566
317 + 2147501249 = 2147501566
389 + 2147501177 = 2147501566
557 + 2147501009 = 2147501566
659 + 2147500907 = 2147501566
677 + 2147500889 = 2147501566

Showing the first eight; more decompositions exist.
