Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533848, here are decompositions:

19 + 31533829 = 31533848
79 + 31533769 = 31533848
127 + 31533721 = 31533848
211 + 31533637 = 31533848
277 + 31533571 = 31533848
331 + 31533517 = 31533848
337 + 31533511 = 31533848
349 + 31533499 = 31533848

Showing the first eight; more decompositions exist.
