Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583514, here are decompositions:

5 + 31583509 = 31583514
7 + 31583507 = 31583514
37 + 31583477 = 31583514
101 + 31583413 = 31583514
163 + 31583351 = 31583514
191 + 31583323 = 31583514
233 + 31583281 = 31583514
257 + 31583257 = 31583514

Showing the first eight; more decompositions exist.
