Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583746, here are decompositions:

17 + 31583729 = 31583746
53 + 31583693 = 31583746
59 + 31583687 = 31583746
83 + 31583663 = 31583746
113 + 31583633 = 31583746
149 + 31583597 = 31583746
197 + 31583549 = 31583746
239 + 31583507 = 31583746

Showing the first eight; more decompositions exist.
