Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583922, here are decompositions:

11 + 31583911 = 31583922
59 + 31583863 = 31583922
103 + 31583819 = 31583922
113 + 31583809 = 31583922
151 + 31583771 = 31583922
173 + 31583749 = 31583922
193 + 31583729 = 31583922
229 + 31583693 = 31583922

Showing the first eight; more decompositions exist.
