Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488532, here are decompositions:

103 + 2147488429 = 2147488532
151 + 2147488381 = 2147488532
199 + 2147488333 = 2147488532
283 + 2147488249 = 2147488532
379 + 2147488153 = 2147488532
421 + 2147488111 = 2147488532
523 + 2147488009 = 2147488532
601 + 2147487931 = 2147488532

Showing the first eight; more decompositions exist.
