Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584656, here are decompositions:

3 + 31584653 = 31584656
43 + 31584613 = 31584656
79 + 31584577 = 31584656
97 + 31584559 = 31584656
109 + 31584547 = 31584656
157 + 31584499 = 31584656
199 + 31584457 = 31584656
283 + 31584373 = 31584656

Showing the first eight; more decompositions exist.
