Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492258, here are decompositions:

101 + 31492157 = 31492258
167 + 31492091 = 31492258
179 + 31492079 = 31492258
191 + 31492067 = 31492258
197 + 31492061 = 31492258
227 + 31492031 = 31492258
269 + 31491989 = 31492258
467 + 31491791 = 31492258

Showing the first eight; more decompositions exist.
