Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492246, here are decompositions:

3 + 31492243 = 31492246
83 + 31492163 = 31492246
89 + 31492157 = 31492246
167 + 31492079 = 31492246
173 + 31492073 = 31492246
179 + 31492067 = 31492246
257 + 31491989 = 31492246
263 + 31491983 = 31492246

Showing the first eight; more decompositions exist.
