Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567090, here are decompositions:

3 + 31567087 = 31567090
41 + 31567049 = 31567090
47 + 31567043 = 31567090
179 + 31566911 = 31567090
227 + 31566863 = 31567090
251 + 31566839 = 31567090
263 + 31566827 = 31567090
293 + 31566797 = 31567090

Showing the first eight; more decompositions exist.
