Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583710, here are decompositions:

17 + 31583693 = 31583710
23 + 31583687 = 31583710
47 + 31583663 = 31583710
83 + 31583627 = 31583710
89 + 31583621 = 31583710
113 + 31583597 = 31583710
149 + 31583561 = 31583710
233 + 31583477 = 31583710

Showing the first eight; more decompositions exist.
