Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564112, here are decompositions:

61 + 31564051 = 31564112
103 + 31564009 = 31564112
163 + 31563949 = 31564112
241 + 31563871 = 31564112
379 + 31563733 = 31564112
661 + 31563451 = 31564112
709 + 31563403 = 31564112
829 + 31563283 = 31564112

Showing the first eight; more decompositions exist.
