Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533752, here are decompositions:

31 + 31533721 = 31533752
139 + 31533613 = 31533752
181 + 31533571 = 31533752
241 + 31533511 = 31533752
373 + 31533379 = 31533752
409 + 31533343 = 31533752
619 + 31533133 = 31533752
661 + 31533091 = 31533752

Showing the first eight; more decompositions exist.
