Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583522, here are decompositions:

13 + 31583509 = 31583522
73 + 31583449 = 31583522
109 + 31583413 = 31583522
199 + 31583323 = 31583522
241 + 31583281 = 31583522
499 + 31583023 = 31583522
541 + 31582981 = 31583522
571 + 31582951 = 31583522

Showing the first eight; more decompositions exist.
