Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564082, here are decompositions:

3 + 31564079 = 31564082
31 + 31564051 = 31564082
73 + 31564009 = 31564082
103 + 31563979 = 31564082
139 + 31563943 = 31564082
211 + 31563871 = 31564082
349 + 31563733 = 31564082
619 + 31563463 = 31564082

Showing the first eight; more decompositions exist.
