Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490538, here are decompositions:

449 + 2147490089 = 2147490538
461 + 2147490077 = 2147490538
569 + 2147489969 = 2147490538
719 + 2147489819 = 2147490538
821 + 2147489717 = 2147490538
839 + 2147489699 = 2147490538
887 + 2147489651 = 2147490538
1097 + 2147489441 = 2147490538

Showing the first eight; more decompositions exist.
