Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533770, here are decompositions:

7 + 31533763 = 31533770
109 + 31533661 = 31533770
139 + 31533631 = 31533770
157 + 31533613 = 31533770
199 + 31533571 = 31533770
223 + 31533547 = 31533770
271 + 31533499 = 31533770
643 + 31533127 = 31533770

Showing the first eight; more decompositions exist.
