Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622724, here are decompositions:

11 + 31622713 = 31622724
31 + 31622693 = 31622724
37 + 31622687 = 31622724
41 + 31622683 = 31622724
53 + 31622671 = 31622724
61 + 31622663 = 31622724
83 + 31622641 = 31622724
233 + 31622491 = 31622724

Showing the first eight; more decompositions exist.
