Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533416, here are decompositions:

3 + 31533413 = 31533416
7 + 31533409 = 31533416
37 + 31533379 = 31533416
73 + 31533343 = 31533416
157 + 31533259 = 31533416
283 + 31533133 = 31533416
457 + 31532959 = 31533416
757 + 31532659 = 31533416

Showing the first eight; more decompositions exist.
