Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533268, here are decompositions:

59 + 31533209 = 31533268
101 + 31533167 = 31533268
149 + 31533119 = 31533268
167 + 31533101 = 31533268
269 + 31532999 = 31533268
401 + 31532867 = 31533268
491 + 31532777 = 31533268
761 + 31532507 = 31533268

Showing the first eight; more decompositions exist.
