Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567420, here are decompositions:

23 + 31567397 = 31567420
107 + 31567313 = 31567420
149 + 31567271 = 31567420
179 + 31567241 = 31567420
263 + 31567157 = 31567420
509 + 31566911 = 31567420
557 + 31566863 = 31567420
593 + 31566827 = 31567420

Showing the first eight; more decompositions exist.
