Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583734, here are decompositions:

5 + 31583729 = 31583734
41 + 31583693 = 31583734
47 + 31583687 = 31583734
71 + 31583663 = 31583734
101 + 31583633 = 31583734
107 + 31583627 = 31583734
113 + 31583621 = 31583734
137 + 31583597 = 31583734

Showing the first eight; more decompositions exist.
