Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534816, here are decompositions:

17 + 31534799 = 31534816
29 + 31534787 = 31534816
59 + 31534757 = 31534816
107 + 31534709 = 31534816
179 + 31534637 = 31534816
227 + 31534589 = 31534816
263 + 31534553 = 31534816
359 + 31534457 = 31534816

Showing the first eight; more decompositions exist.
