Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535322, here are decompositions:

11 + 31535311 = 31535322
59 + 31535263 = 31535322
89 + 31535233 = 31535322
103 + 31535219 = 31535322
109 + 31535213 = 31535322
139 + 31535183 = 31535322
149 + 31535173 = 31535322
151 + 31535171 = 31535322

Showing the first eight; more decompositions exist.
