Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567216, here are decompositions:

3 + 31567213 = 31567216
59 + 31567157 = 31567216
167 + 31567049 = 31567216
173 + 31567043 = 31567216
353 + 31566863 = 31567216
389 + 31566827 = 31567216
419 + 31566797 = 31567216
467 + 31566749 = 31567216

Showing the first eight; more decompositions exist.
