Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567270, here are decompositions:

3 + 31567267 = 31567270
29 + 31567241 = 31567270
113 + 31567157 = 31567270
179 + 31567091 = 31567270
227 + 31567043 = 31567270
359 + 31566911 = 31567270
431 + 31566839 = 31567270
443 + 31566827 = 31567270

Showing the first eight; more decompositions exist.
