Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489122, here are decompositions:

263 + 2147488859 = 2147489122
431 + 2147488691 = 2147489122
479 + 2147488643 = 2147489122
503 + 2147488619 = 2147489122
509 + 2147488613 = 2147489122
563 + 2147488559 = 2147489122
971 + 2147488151 = 2147489122
1061 + 2147488061 = 2147489122

Showing the first eight; more decompositions exist.
