Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583496, here are decompositions:

19 + 31583477 = 31583496
47 + 31583449 = 31583496
59 + 31583437 = 31583496
73 + 31583423 = 31583496
83 + 31583413 = 31583496
173 + 31583323 = 31583496
227 + 31583269 = 31583496
239 + 31583257 = 31583496

Showing the first eight; more decompositions exist.
