Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584722, here are decompositions:

19 + 31584703 = 31584722
109 + 31584613 = 31584722
163 + 31584559 = 31584722
181 + 31584541 = 31584722
199 + 31584523 = 31584722
223 + 31584499 = 31584722
241 + 31584481 = 31584722
283 + 31584439 = 31584722

Showing the first eight; more decompositions exist.
