Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567096, here are decompositions:

5 + 31567091 = 31567096
47 + 31567049 = 31567096
53 + 31567043 = 31567096
233 + 31566863 = 31567096
257 + 31566839 = 31567096
269 + 31566827 = 31567096
293 + 31566803 = 31567096
347 + 31566749 = 31567096

Showing the first eight; more decompositions exist.
