Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567272, here are decompositions:

5 + 31567267 = 31567272
31 + 31567241 = 31567272
41 + 31567231 = 31567272
53 + 31567219 = 31567272
59 + 31567213 = 31567272
181 + 31567091 = 31567272
223 + 31567049 = 31567272
229 + 31567043 = 31567272

Showing the first eight; more decompositions exist.
