Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506536, here are decompositions:

7 + 31506529 = 31506536
13 + 31506523 = 31506536
163 + 31506373 = 31506536
433 + 31506103 = 31506536
547 + 31505989 = 31506536
577 + 31505959 = 31506536
613 + 31505923 = 31506536
727 + 31505809 = 31506536

Showing the first eight; more decompositions exist.
