Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496412, here are decompositions:

23 + 31496389 = 31496412
41 + 31496371 = 31496412
43 + 31496369 = 31496412
83 + 31496329 = 31496412
149 + 31496263 = 31496412
151 + 31496261 = 31496412
191 + 31496221 = 31496412
193 + 31496219 = 31496412

Showing the first eight; more decompositions exist.
