Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564202, here are decompositions:

31 + 31564171 = 31564202
73 + 31564129 = 31564202
151 + 31564051 = 31564202
193 + 31564009 = 31564202
223 + 31563979 = 31564202
331 + 31563871 = 31564202
409 + 31563793 = 31564202
601 + 31563601 = 31564202

Showing the first eight; more decompositions exist.
