Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533358, here are decompositions:

89 + 31533269 = 31533358
149 + 31533209 = 31533358
167 + 31533191 = 31533358
191 + 31533167 = 31533358
239 + 31533119 = 31533358
257 + 31533101 = 31533358
359 + 31532999 = 31533358
419 + 31532939 = 31533358

Showing the first eight; more decompositions exist.
