Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535046, here are decompositions:

13 + 31535033 = 31535046
47 + 31534999 = 31535046
167 + 31534879 = 31535046
173 + 31534873 = 31535046
227 + 31534819 = 31535046
293 + 31534753 = 31535046
307 + 31534739 = 31535046
317 + 31534729 = 31535046

Showing the first eight; more decompositions exist.
