Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564422, here are decompositions:

31 + 31564391 = 31564422
61 + 31564361 = 31564422
89 + 31564333 = 31564422
101 + 31564321 = 31564422
151 + 31564271 = 31564422
173 + 31564249 = 31564422
179 + 31564243 = 31564422
181 + 31564241 = 31564422

Showing the first eight; more decompositions exist.
