Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533686, here are decompositions:

73 + 31533613 = 31533686
139 + 31533547 = 31533686
277 + 31533409 = 31533686
307 + 31533379 = 31533686
673 + 31533013 = 31533686
727 + 31532959 = 31533686
787 + 31532899 = 31533686
823 + 31532863 = 31533686

Showing the first eight; more decompositions exist.
