Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567394, here are decompositions:

97 + 31567297 = 31567394
127 + 31567267 = 31567394
163 + 31567231 = 31567394
181 + 31567213 = 31567394
241 + 31567153 = 31567394
307 + 31567087 = 31567394
421 + 31566973 = 31567394
577 + 31566817 = 31567394

Showing the first eight; more decompositions exist.
