Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492336, here are decompositions:

17 + 31492319 = 31492336
59 + 31492277 = 31492336
173 + 31492163 = 31492336
179 + 31492157 = 31492336
257 + 31492079 = 31492336
263 + 31492073 = 31492336
269 + 31492067 = 31492336
347 + 31491989 = 31492336

Showing the first eight; more decompositions exist.
