Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564062, here are decompositions:

11 + 31564051 = 31564062
53 + 31564009 = 31564062
73 + 31563989 = 31564062
83 + 31563979 = 31564062
109 + 31563953 = 31564062
113 + 31563949 = 31564062
151 + 31563911 = 31564062
163 + 31563899 = 31564062

Showing the first eight; more decompositions exist.
