Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492022, here are decompositions:

109 + 31491913 = 31492022
181 + 31491841 = 31492022
229 + 31491793 = 31492022
409 + 31491613 = 31492022
433 + 31491589 = 31492022
691 + 31491331 = 31492022
733 + 31491289 = 31492022
739 + 31491283 = 31492022

Showing the first eight; more decompositions exist.
