Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532328, here are decompositions:

5 + 31532323 = 31532328
59 + 31532269 = 31532328
67 + 31532261 = 31532328
101 + 31532227 = 31532328
109 + 31532219 = 31532328
211 + 31532117 = 31532328
239 + 31532089 = 31532328
257 + 31532071 = 31532328

Showing the first eight; more decompositions exist.
