Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567916, here are decompositions:

67 + 31567849 = 31567916
97 + 31567819 = 31567916
103 + 31567813 = 31567916
199 + 31567717 = 31567916
223 + 31567693 = 31567916
229 + 31567687 = 31567916
313 + 31567603 = 31567916
487 + 31567429 = 31567916

Showing the first eight; more decompositions exist.
