Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533548, here are decompositions:

31 + 31533517 = 31533548
37 + 31533511 = 31533548
97 + 31533451 = 31533548
139 + 31533409 = 31533548
421 + 31533127 = 31533548
457 + 31533091 = 31533548
547 + 31533001 = 31533548
577 + 31532971 = 31533548

Showing the first eight; more decompositions exist.
