Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583706, here are decompositions:

5 + 31583701 = 31583706
13 + 31583693 = 31583706
19 + 31583687 = 31583706
43 + 31583663 = 31583706
47 + 31583659 = 31583706
73 + 31583633 = 31583706
79 + 31583627 = 31583706
109 + 31583597 = 31583706

Showing the first eight; more decompositions exist.
