Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492112, here are decompositions:

19 + 31492093 = 31492112
31 + 31492081 = 31492112
61 + 31492051 = 31492112
79 + 31492033 = 31492112
199 + 31491913 = 31492112
271 + 31491841 = 31492112
433 + 31491679 = 31492112
499 + 31491613 = 31492112

Showing the first eight; more decompositions exist.
