Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496352, here are decompositions:

23 + 31496329 = 31496352
31 + 31496321 = 31496352
59 + 31496293 = 31496352
89 + 31496263 = 31496352
131 + 31496221 = 31496352
179 + 31496173 = 31496352
191 + 31496161 = 31496352
211 + 31496141 = 31496352

Showing the first eight; more decompositions exist.
