Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583674, here are decompositions:

11 + 31583663 = 31583674
41 + 31583633 = 31583674
47 + 31583627 = 31583674
53 + 31583621 = 31583674
113 + 31583561 = 31583674
167 + 31583507 = 31583674
197 + 31583477 = 31583674
251 + 31583423 = 31583674

Showing the first eight; more decompositions exist.
