Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535222, here are decompositions:

3 + 31535219 = 31535222
79 + 31535143 = 31535222
109 + 31535113 = 31535222
139 + 31535083 = 31535222
163 + 31535059 = 31535222
211 + 31535011 = 31535222
223 + 31534999 = 31535222
241 + 31534981 = 31535222

Showing the first eight; more decompositions exist.
