Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488718, here are decompositions:

139 + 2147488579 = 2147488718
307 + 2147488411 = 2147488718
337 + 2147488381 = 2147488718
439 + 2147488279 = 2147488718
547 + 2147488171 = 2147488718
607 + 2147488111 = 2147488718
691 + 2147488027 = 2147488718
709 + 2147488009 = 2147488718

Showing the first eight; more decompositions exist.
