Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535916, here are decompositions:

7 + 31535909 = 31535916
37 + 31535879 = 31535916
89 + 31535827 = 31535916
107 + 31535809 = 31535916
163 + 31535753 = 31535916
199 + 31535717 = 31535916
277 + 31535639 = 31535916
283 + 31535633 = 31535916

Showing the first eight; more decompositions exist.
