Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489938, here are decompositions:

29 + 2147489909 = 2147489938
89 + 2147489849 = 2147489938
239 + 2147489699 = 2147489938
359 + 2147489579 = 2147489938
401 + 2147489537 = 2147489938
641 + 2147489297 = 2147489938
647 + 2147489291 = 2147489938
941 + 2147488997 = 2147489938

Showing the first eight; more decompositions exist.
