Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533294, here are decompositions:

103 + 31533191 = 31533294
127 + 31533167 = 31533294
151 + 31533143 = 31533294
167 + 31533127 = 31533294
193 + 31533101 = 31533294
197 + 31533097 = 31533294
281 + 31533013 = 31533294
293 + 31533001 = 31533294

Showing the first eight; more decompositions exist.
