Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626122, here are decompositions:

13 + 31626109 = 31626122
43 + 31626079 = 31626122
103 + 31626019 = 31626122
211 + 31625911 = 31626122
349 + 31625773 = 31626122
523 + 31625599 = 31626122
613 + 31625509 = 31626122
691 + 31625431 = 31626122

Showing the first eight; more decompositions exist.
