Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567060, here are decompositions:

11 + 31567049 = 31567060
17 + 31567043 = 31567060
149 + 31566911 = 31567060
197 + 31566863 = 31567060
233 + 31566827 = 31567060
257 + 31566803 = 31567060
263 + 31566797 = 31567060
311 + 31566749 = 31567060

Showing the first eight; more decompositions exist.
