Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583682, here are decompositions:

19 + 31583663 = 31583682
23 + 31583659 = 31583682
41 + 31583641 = 31583682
61 + 31583621 = 31583682
173 + 31583509 = 31583682
233 + 31583449 = 31583682
269 + 31583413 = 31583682
331 + 31583351 = 31583682

Showing the first eight; more decompositions exist.
