Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568022, here are decompositions:

23 + 31567999 = 31568022
41 + 31567981 = 31568022
61 + 31567961 = 31568022
139 + 31567883 = 31568022
163 + 31567859 = 31568022
173 + 31567849 = 31568022
281 + 31567741 = 31568022
293 + 31567729 = 31568022

Showing the first eight; more decompositions exist.
