Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622810, here are decompositions:

7 + 31622803 = 31622810
31 + 31622779 = 31622810
67 + 31622743 = 31622810
97 + 31622713 = 31622810
127 + 31622683 = 31622810
139 + 31622671 = 31622810
181 + 31622629 = 31622810
211 + 31622599 = 31622810

Showing the first eight; more decompositions exist.
