Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564076, here are decompositions:

67 + 31564009 = 31564076
97 + 31563979 = 31564076
109 + 31563967 = 31564076
127 + 31563949 = 31564076
139 + 31563937 = 31564076
199 + 31563877 = 31564076
283 + 31563793 = 31564076
613 + 31563463 = 31564076

Showing the first eight; more decompositions exist.
