Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583794, here are decompositions:

17 + 31583777 = 31583794
23 + 31583771 = 31583794
41 + 31583753 = 31583794
101 + 31583693 = 31583794
107 + 31583687 = 31583794
131 + 31583663 = 31583794
167 + 31583627 = 31583794
173 + 31583621 = 31583794

Showing the first eight; more decompositions exist.
