Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583436, here are decompositions:

13 + 31583423 = 31583436
23 + 31583413 = 31583436
83 + 31583353 = 31583436
113 + 31583323 = 31583436
167 + 31583269 = 31583436
179 + 31583257 = 31583436
277 + 31583159 = 31583436
349 + 31583087 = 31583436

Showing the first eight; more decompositions exist.
