Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566536, here are decompositions:

13 + 31566523 = 31566536
19 + 31566517 = 31566536
109 + 31566427 = 31566536
139 + 31566397 = 31566536
367 + 31566169 = 31566536
457 + 31566079 = 31566536
523 + 31566013 = 31566536
607 + 31565929 = 31566536

Showing the first eight; more decompositions exist.
