Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488782, here are decompositions:

31 + 2147488751 = 2147488782
41 + 2147488741 = 2147488782
139 + 2147488643 = 2147488782
163 + 2147488619 = 2147488782
223 + 2147488559 = 2147488782
239 + 2147488543 = 2147488782
353 + 2147488429 = 2147488782
401 + 2147488381 = 2147488782

Showing the first eight; more decompositions exist.
