Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622646, here are decompositions:

5 + 31622641 = 31622646
17 + 31622629 = 31622646
47 + 31622599 = 31622646
67 + 31622579 = 31622646
109 + 31622537 = 31622646
127 + 31622519 = 31622646
137 + 31622509 = 31622646
173 + 31622473 = 31622646

Showing the first eight; more decompositions exist.
