Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533352, here are decompositions:

83 + 31533269 = 31533352
233 + 31533119 = 31533352
251 + 31533101 = 31533352
353 + 31532999 = 31533352
479 + 31532873 = 31533352
659 + 31532693 = 31533352
863 + 31532489 = 31533352
1013 + 31532339 = 31533352

Showing the first eight; more decompositions exist.
