Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583662, here are decompositions:

3 + 31583659 = 31583662
29 + 31583633 = 31583662
41 + 31583621 = 31583662
101 + 31583561 = 31583662
113 + 31583549 = 31583662
239 + 31583423 = 31583662
311 + 31583351 = 31583662
491 + 31583171 = 31583662

Showing the first eight; more decompositions exist.
