Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533318, here are decompositions:

59 + 31533259 = 31533318
109 + 31533209 = 31533318
127 + 31533191 = 31533318
151 + 31533167 = 31533318
191 + 31533127 = 31533318
199 + 31533119 = 31533318
227 + 31533091 = 31533318
317 + 31533001 = 31533318

Showing the first eight; more decompositions exist.
