Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535016, here are decompositions:

5 + 31535011 = 31535016
17 + 31534999 = 31535016
103 + 31534913 = 31535016
137 + 31534879 = 31535016
197 + 31534819 = 31535016
229 + 31534787 = 31535016
263 + 31534753 = 31535016
277 + 31534739 = 31535016

Showing the first eight; more decompositions exist.
