Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567822, here are decompositions:

3 + 31567819 = 31567822
53 + 31567769 = 31567822
113 + 31567709 = 31567822
149 + 31567673 = 31567822
173 + 31567649 = 31567822
179 + 31567643 = 31567822
263 + 31567559 = 31567822
269 + 31567553 = 31567822

Showing the first eight; more decompositions exist.
