Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583516, here are decompositions:

7 + 31583509 = 31583516
67 + 31583449 = 31583516
79 + 31583437 = 31583516
103 + 31583413 = 31583516
163 + 31583353 = 31583516
193 + 31583323 = 31583516
379 + 31583137 = 31583516
619 + 31582897 = 31583516

Showing the first eight; more decompositions exist.
