Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583456, here are decompositions:

7 + 31583449 = 31583456
19 + 31583437 = 31583456
43 + 31583413 = 31583456
103 + 31583353 = 31583456
199 + 31583257 = 31583456
409 + 31583047 = 31583456
433 + 31583023 = 31583456
727 + 31582729 = 31583456

Showing the first eight; more decompositions exist.
