Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599916, here are decompositions:

3 + 31599913 = 31599916
107 + 31599809 = 31599916
149 + 31599767 = 31599916
233 + 31599683 = 31599916
263 + 31599653 = 31599916
317 + 31599599 = 31599916
353 + 31599563 = 31599916
563 + 31599353 = 31599916

Showing the first eight; more decompositions exist.
