Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488564, here are decompositions:

5 + 2147488559 = 2147488564
47 + 2147488517 = 2147488564
257 + 2147488307 = 2147488564
317 + 2147488247 = 2147488564
401 + 2147488163 = 2147488564
503 + 2147488061 = 2147488564
521 + 2147488043 = 2147488564
563 + 2147488001 = 2147488564

Showing the first eight; more decompositions exist.
