Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533458, here are decompositions:

7 + 31533451 = 31533458
79 + 31533379 = 31533458
199 + 31533259 = 31533458
331 + 31533127 = 31533458
367 + 31533091 = 31533458
457 + 31533001 = 31533458
487 + 31532971 = 31533458
499 + 31532959 = 31533458

Showing the first eight; more decompositions exist.
