Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583748, here are decompositions:

19 + 31583729 = 31583748
47 + 31583701 = 31583748
61 + 31583687 = 31583748
89 + 31583659 = 31583748
107 + 31583641 = 31583748
127 + 31583621 = 31583748
151 + 31583597 = 31583748
199 + 31583549 = 31583748

Showing the first eight; more decompositions exist.
