Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492294, here are decompositions:

17 + 31492277 = 31492294
131 + 31492163 = 31492294
137 + 31492157 = 31492294
227 + 31492067 = 31492294
233 + 31492061 = 31492294
263 + 31492031 = 31492294
311 + 31491983 = 31492294
401 + 31491893 = 31492294

Showing the first eight; more decompositions exist.
