Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583814, here are decompositions:

5 + 31583809 = 31583814
11 + 31583803 = 31583814
37 + 31583777 = 31583814
43 + 31583771 = 31583814
61 + 31583753 = 31583814
113 + 31583701 = 31583814
127 + 31583687 = 31583814
151 + 31583663 = 31583814

Showing the first eight; more decompositions exist.
