Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583926, here are decompositions:

5 + 31583921 = 31583926
29 + 31583897 = 31583926
89 + 31583837 = 31583926
107 + 31583819 = 31583926
149 + 31583777 = 31583926
173 + 31583753 = 31583926
197 + 31583729 = 31583926
233 + 31583693 = 31583926

Showing the first eight; more decompositions exist.
