Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583584, here are decompositions:

23 + 31583561 = 31583584
107 + 31583477 = 31583584
233 + 31583351 = 31583584
503 + 31583081 = 31583584
647 + 31582937 = 31583584
653 + 31582931 = 31583584
677 + 31582907 = 31583584
761 + 31582823 = 31583584

Showing the first eight; more decompositions exist.
