Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567404, here are decompositions:

7 + 31567397 = 31567404
107 + 31567297 = 31567404
137 + 31567267 = 31567404
163 + 31567241 = 31567404
173 + 31567231 = 31567404
191 + 31567213 = 31567404
251 + 31567153 = 31567404
313 + 31567091 = 31567404

Showing the first eight; more decompositions exist.
