Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530848, here are decompositions:

7 + 31530841 = 31530848
199 + 31530649 = 31530848
211 + 31530637 = 31530848
241 + 31530607 = 31530848
277 + 31530571 = 31530848
397 + 31530451 = 31530848
439 + 31530409 = 31530848
457 + 31530391 = 31530848

Showing the first eight; more decompositions exist.
