Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583468, here are decompositions:

19 + 31583449 = 31583468
31 + 31583437 = 31583468
199 + 31583269 = 31583468
211 + 31583257 = 31583468
331 + 31583137 = 31583468
337 + 31583131 = 31583468
421 + 31583047 = 31583468
487 + 31582981 = 31583468

Showing the first eight; more decompositions exist.
