Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488538, here are decompositions:

109 + 2147488429 = 2147488538
127 + 2147488411 = 2147488538
157 + 2147488381 = 2147488538
367 + 2147488171 = 2147488538
607 + 2147487931 = 2147488538
631 + 2147487907 = 2147488538
709 + 2147487829 = 2147488538
739 + 2147487799 = 2147488538

Showing the first eight; more decompositions exist.
