Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583676, here are decompositions:

13 + 31583663 = 31583676
17 + 31583659 = 31583676
43 + 31583633 = 31583676
79 + 31583597 = 31583676
127 + 31583549 = 31583676
149 + 31583527 = 31583676
167 + 31583509 = 31583676
199 + 31583477 = 31583676

Showing the first eight; more decompositions exist.
