Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567108, here are decompositions:

17 + 31567091 = 31567108
59 + 31567049 = 31567108
197 + 31566911 = 31567108
269 + 31566839 = 31567108
281 + 31566827 = 31567108
311 + 31566797 = 31567108
359 + 31566749 = 31567108
449 + 31566659 = 31567108

Showing the first eight; more decompositions exist.
