Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466986, here are decompositions:

17 + 31466969 = 31466986
53 + 31466933 = 31466986
113 + 31466873 = 31466986
137 + 31466849 = 31466986
227 + 31466759 = 31466986
233 + 31466753 = 31466986
293 + 31466693 = 31466986
359 + 31466627 = 31466986

Showing the first eight; more decompositions exist.
