Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622744, here are decompositions:

3 + 31622741 = 31622744
31 + 31622713 = 31622744
61 + 31622683 = 31622744
73 + 31622671 = 31622744
103 + 31622641 = 31622744
271 + 31622473 = 31622744
277 + 31622467 = 31622744
367 + 31622377 = 31622744

Showing the first eight; more decompositions exist.
