Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627566, here are decompositions:

7 + 31627559 = 31627566
23 + 31627543 = 31627566
29 + 31627537 = 31627566
83 + 31627483 = 31627566
193 + 31627373 = 31627566
233 + 31627333 = 31627566
263 + 31627303 = 31627566
277 + 31627289 = 31627566

Showing the first eight; more decompositions exist.
