Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492262, here are decompositions:

3 + 31492259 = 31492262
19 + 31492243 = 31492262
181 + 31492081 = 31492262
211 + 31492051 = 31492262
229 + 31492033 = 31492262
349 + 31491913 = 31492262
421 + 31491841 = 31492262
601 + 31491661 = 31492262

Showing the first eight; more decompositions exist.
