Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492270, here are decompositions:

11 + 31492259 = 31492270
107 + 31492163 = 31492270
113 + 31492157 = 31492270
179 + 31492091 = 31492270
191 + 31492079 = 31492270
197 + 31492073 = 31492270
239 + 31492031 = 31492270
281 + 31491989 = 31492270

Showing the first eight; more decompositions exist.
