Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492252, here are decompositions:

89 + 31492163 = 31492252
173 + 31492079 = 31492252
179 + 31492073 = 31492252
191 + 31492061 = 31492252
263 + 31491989 = 31492252
269 + 31491983 = 31492252
293 + 31491959 = 31492252
359 + 31491893 = 31492252

Showing the first eight; more decompositions exist.
