Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559022, here are decompositions:

29 + 31558993 = 31559022
59 + 31558963 = 31559022
83 + 31558939 = 31559022
139 + 31558883 = 31559022
163 + 31558859 = 31559022
179 + 31558843 = 31559022
191 + 31558831 = 31559022
199 + 31558823 = 31559022

Showing the first eight; more decompositions exist.
