Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496406, here are decompositions:

17 + 31496389 = 31496406
37 + 31496369 = 31496406
89 + 31496317 = 31496406
113 + 31496293 = 31496406
197 + 31496209 = 31496406
233 + 31496173 = 31496406
283 + 31496123 = 31496406
307 + 31496099 = 31496406

Showing the first eight; more decompositions exist.
