Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583374, here are decompositions:

23 + 31583351 = 31583374
227 + 31583147 = 31583374
293 + 31583081 = 31583374
443 + 31582931 = 31583374
461 + 31582913 = 31583374
467 + 31582907 = 31583374
593 + 31582781 = 31583374
617 + 31582757 = 31583374

Showing the first eight; more decompositions exist.
