Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489236, here are decompositions:

29 + 2147489207 = 2147489236
149 + 2147489087 = 2147489236
239 + 2147488997 = 2147489236
317 + 2147488919 = 2147489236
443 + 2147488793 = 2147489236
509 + 2147488727 = 2147489236
593 + 2147488643 = 2147489236
617 + 2147488619 = 2147489236

Showing the first eight; more decompositions exist.
