Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492202, here are decompositions:

109 + 31492093 = 31492202
151 + 31492051 = 31492202
409 + 31491793 = 31492202
523 + 31491679 = 31492202
541 + 31491661 = 31492202
613 + 31491589 = 31492202
631 + 31491571 = 31492202
691 + 31491511 = 31492202

Showing the first eight; more decompositions exist.
