Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533746, here are decompositions:

109 + 31533637 = 31533746
199 + 31533547 = 31533746
229 + 31533517 = 31533746
337 + 31533409 = 31533746
367 + 31533379 = 31533746
487 + 31533259 = 31533746
613 + 31533133 = 31533746
619 + 31533127 = 31533746

Showing the first eight; more decompositions exist.
