Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489566, here are decompositions:

23 + 2147489543 = 2147489566
29 + 2147489537 = 2147489566
83 + 2147489483 = 2147489566
269 + 2147489297 = 2147489566
359 + 2147489207 = 2147489566
479 + 2147489087 = 2147489566
569 + 2147488997 = 2147489566
647 + 2147488919 = 2147489566

Showing the first eight; more decompositions exist.
