Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492244, here are decompositions:

31 + 31492213 = 31492244
151 + 31492093 = 31492244
163 + 31492081 = 31492244
193 + 31492051 = 31492244
211 + 31492033 = 31492244
331 + 31491913 = 31492244
457 + 31491787 = 31492244
547 + 31491697 = 31492244

Showing the first eight; more decompositions exist.
