Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564106, here are decompositions:

3 + 31564103 = 31564106
97 + 31564009 = 31564106
127 + 31563979 = 31564106
139 + 31563967 = 31564106
157 + 31563949 = 31564106
163 + 31563943 = 31564106
199 + 31563907 = 31564106
229 + 31563877 = 31564106

Showing the first eight; more decompositions exist.
