Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533068, here are decompositions:

67 + 31533001 = 31533068
97 + 31532971 = 31533068
109 + 31532959 = 31533068
331 + 31532737 = 31533068
409 + 31532659 = 31533068
487 + 31532581 = 31533068
547 + 31532521 = 31533068
571 + 31532497 = 31533068

Showing the first eight; more decompositions exist.
