Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567260, here are decompositions:

19 + 31567241 = 31567260
29 + 31567231 = 31567260
41 + 31567219 = 31567260
47 + 31567213 = 31567260
103 + 31567157 = 31567260
107 + 31567153 = 31567260
173 + 31567087 = 31567260
211 + 31567049 = 31567260

Showing the first eight; more decompositions exist.
