Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567422, here are decompositions:

11 + 31567411 = 31567422
53 + 31567369 = 31567422
109 + 31567313 = 31567422
151 + 31567271 = 31567422
181 + 31567241 = 31567422
191 + 31567231 = 31567422
269 + 31567153 = 31567422
331 + 31567091 = 31567422

Showing the first eight; more decompositions exist.
