Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584956, here are decompositions:

3 + 31584953 = 31584956
103 + 31584853 = 31584956
127 + 31584829 = 31584956
199 + 31584757 = 31584956
349 + 31584607 = 31584956
379 + 31584577 = 31584956
397 + 31584559 = 31584956
409 + 31584547 = 31584956

Showing the first eight; more decompositions exist.
