Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598022, here are decompositions:

11 + 31598011 = 31598022
13 + 31598009 = 31598022
61 + 31597961 = 31598022
89 + 31597933 = 31598022
109 + 31597913 = 31598022
149 + 31597873 = 31598022
179 + 31597843 = 31598022
199 + 31597823 = 31598022

Showing the first eight; more decompositions exist.
