Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533644, here are decompositions:

3 + 31533641 = 31533644
7 + 31533637 = 31533644
13 + 31533631 = 31533644
31 + 31533613 = 31533644
73 + 31533571 = 31533644
97 + 31533547 = 31533644
127 + 31533517 = 31533644
193 + 31533451 = 31533644

Showing the first eight; more decompositions exist.
