Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533292, here are decompositions:

23 + 31533269 = 31533292
83 + 31533209 = 31533292
101 + 31533191 = 31533292
149 + 31533143 = 31533292
173 + 31533119 = 31533292
191 + 31533101 = 31533292
293 + 31532999 = 31533292
311 + 31532981 = 31533292

Showing the first eight; more decompositions exist.
