Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489068, here are decompositions:

71 + 2147488997 = 2147489068
149 + 2147488919 = 2147489068
317 + 2147488751 = 2147489068
449 + 2147488619 = 2147489068
509 + 2147488559 = 2147489068
761 + 2147488307 = 2147489068
821 + 2147488247 = 2147489068
1289 + 2147487779 = 2147489068

Showing the first eight; more decompositions exist.
