Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622682, here are decompositions:

11 + 31622671 = 31622682
19 + 31622663 = 31622682
41 + 31622641 = 31622682
53 + 31622629 = 31622682
83 + 31622599 = 31622682
103 + 31622579 = 31622682
163 + 31622519 = 31622682
173 + 31622509 = 31622682

Showing the first eight; more decompositions exist.
