Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627916, here are decompositions:

13 + 31627903 = 31627916
37 + 31627879 = 31627916
163 + 31627753 = 31627916
277 + 31627639 = 31627916
349 + 31627567 = 31627916
373 + 31627543 = 31627916
379 + 31627537 = 31627916
433 + 31627483 = 31627916

Showing the first eight; more decompositions exist.
