Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547732, here are decompositions:

31 + 31547701 = 31547732
61 + 31547671 = 31547732
103 + 31547629 = 31547732
193 + 31547539 = 31547732
283 + 31547449 = 31547732
523 + 31547209 = 31547732
571 + 31547161 = 31547732
631 + 31547101 = 31547732

Showing the first eight; more decompositions exist.
