Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533086, here are decompositions:

73 + 31533013 = 31533086
127 + 31532959 = 31533086
163 + 31532923 = 31533086
223 + 31532863 = 31533086
337 + 31532749 = 31533086
349 + 31532737 = 31533086
433 + 31532653 = 31533086
499 + 31532587 = 31533086

Showing the first eight; more decompositions exist.
