Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535022, here are decompositions:

11 + 31535011 = 31535022
23 + 31534999 = 31535022
41 + 31534981 = 31535022
61 + 31534961 = 31535022
109 + 31534913 = 31535022
149 + 31534873 = 31535022
151 + 31534871 = 31535022
191 + 31534831 = 31535022

Showing the first eight; more decompositions exist.
