Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530554, here are decompositions:

31 + 31530523 = 31530554
67 + 31530487 = 31530554
103 + 31530451 = 31530554
163 + 31530391 = 31530554
373 + 31530181 = 31530554
457 + 31530097 = 31530554
577 + 31529977 = 31530554
631 + 31529923 = 31530554

Showing the first eight; more decompositions exist.
