Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583466, here are decompositions:

17 + 31583449 = 31583466
29 + 31583437 = 31583466
43 + 31583423 = 31583466
53 + 31583413 = 31583466
113 + 31583353 = 31583466
197 + 31583269 = 31583466
307 + 31583159 = 31583466
379 + 31583087 = 31583466

Showing the first eight; more decompositions exist.
