Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564022, here are decompositions:

13 + 31564009 = 31564022
43 + 31563979 = 31564022
73 + 31563949 = 31564022
79 + 31563943 = 31564022
151 + 31563871 = 31564022
229 + 31563793 = 31564022
421 + 31563601 = 31564022
571 + 31563451 = 31564022

Showing the first eight; more decompositions exist.
