Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492300, here are decompositions:

23 + 31492277 = 31492300
41 + 31492259 = 31492300
137 + 31492163 = 31492300
227 + 31492073 = 31492300
233 + 31492067 = 31492300
239 + 31492061 = 31492300
269 + 31492031 = 31492300
311 + 31491989 = 31492300

Showing the first eight; more decompositions exist.
