Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627732, here are decompositions:

5 + 31627727 = 31627732
11 + 31627721 = 31627732
83 + 31627649 = 31627732
131 + 31627601 = 31627732
173 + 31627559 = 31627732
359 + 31627373 = 31627732
443 + 31627289 = 31627732
599 + 31627133 = 31627732

Showing the first eight; more decompositions exist.
