Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583724, here are decompositions:

23 + 31583701 = 31583724
31 + 31583693 = 31583724
37 + 31583687 = 31583724
61 + 31583663 = 31583724
83 + 31583641 = 31583724
97 + 31583627 = 31583724
103 + 31583621 = 31583724
127 + 31583597 = 31583724

Showing the first eight; more decompositions exist.
