Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622746, here are decompositions:

3 + 31622743 = 31622746
5 + 31622741 = 31622746
17 + 31622729 = 31622746
47 + 31622699 = 31622746
53 + 31622693 = 31622746
59 + 31622687 = 31622746
83 + 31622663 = 31622746
167 + 31622579 = 31622746

Showing the first eight; more decompositions exist.
