Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583694, here are decompositions:

7 + 31583687 = 31583694
31 + 31583663 = 31583694
53 + 31583641 = 31583694
61 + 31583633 = 31583694
67 + 31583627 = 31583694
73 + 31583621 = 31583694
97 + 31583597 = 31583694
167 + 31583527 = 31583694

Showing the first eight; more decompositions exist.
