Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489758, here are decompositions:

41 + 2147489717 = 2147489758
59 + 2147489699 = 2147489758
107 + 2147489651 = 2147489758
179 + 2147489579 = 2147489758
317 + 2147489441 = 2147489758
461 + 2147489297 = 2147489758
467 + 2147489291 = 2147489758
761 + 2147488997 = 2147489758

Showing the first eight; more decompositions exist.
