Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584626, here are decompositions:

13 + 31584613 = 31584626
19 + 31584607 = 31584626
67 + 31584559 = 31584626
79 + 31584547 = 31584626
103 + 31584523 = 31584626
127 + 31584499 = 31584626
379 + 31584247 = 31584626
433 + 31584193 = 31584626

Showing the first eight; more decompositions exist.
