Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496328, here are decompositions:

7 + 31496321 = 31496328
11 + 31496317 = 31496328
67 + 31496261 = 31496328
107 + 31496221 = 31496328
109 + 31496219 = 31496328
167 + 31496161 = 31496328
229 + 31496099 = 31496328
271 + 31496057 = 31496328

Showing the first eight; more decompositions exist.
