Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532286, here are decompositions:

7 + 31532279 = 31532286
17 + 31532269 = 31532286
59 + 31532227 = 31532286
67 + 31532219 = 31532286
83 + 31532203 = 31532286
173 + 31532113 = 31532286
197 + 31532089 = 31532286
223 + 31532063 = 31532286

Showing the first eight; more decompositions exist.
