Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564056, here are decompositions:

5 + 31564051 = 31564056
47 + 31564009 = 31564056
67 + 31563989 = 31564056
89 + 31563967 = 31564056
103 + 31563953 = 31564056
107 + 31563949 = 31564056
109 + 31563947 = 31564056
113 + 31563943 = 31564056

Showing the first eight; more decompositions exist.
