Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489458, here are decompositions:

17 + 2147489441 = 2147489458
167 + 2147489291 = 2147489458
251 + 2147489207 = 2147489458
461 + 2147488997 = 2147489458
599 + 2147488859 = 2147489458
839 + 2147488619 = 2147489458
941 + 2147488517 = 2147489458
1151 + 2147488307 = 2147489458

Showing the first eight; more decompositions exist.
