Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533716, here are decompositions:

79 + 31533637 = 31533716
103 + 31533613 = 31533716
199 + 31533517 = 31533716
307 + 31533409 = 31533716
337 + 31533379 = 31533716
373 + 31533343 = 31533716
457 + 31533259 = 31533716
619 + 31533097 = 31533716

Showing the first eight; more decompositions exist.
