Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506682, here are decompositions:

5 + 31506677 = 31506682
41 + 31506641 = 31506682
83 + 31506599 = 31506682
113 + 31506569 = 31506682
239 + 31506443 = 31506682
419 + 31506263 = 31506682
509 + 31506173 = 31506682
563 + 31506119 = 31506682

Showing the first eight; more decompositions exist.
