Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466886, here are decompositions:

17 + 2147466869 = 2147466886
53 + 2147466833 = 2147466886
347 + 2147466539 = 2147466886
503 + 2147466383 = 2147466886
557 + 2147466329 = 2147466886
647 + 2147466239 = 2147466886
659 + 2147466227 = 2147466886
1019 + 2147465867 = 2147466886

Showing the first eight; more decompositions exist.
