Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564058, here are decompositions:

7 + 31564051 = 31564058
79 + 31563979 = 31564058
109 + 31563949 = 31564058
151 + 31563907 = 31564058
181 + 31563877 = 31564058
241 + 31563817 = 31564058
271 + 31563787 = 31564058
457 + 31563601 = 31564058

Showing the first eight; more decompositions exist.
