Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496466, here are decompositions:

17 + 31496449 = 31496466
37 + 31496429 = 31496466
47 + 31496419 = 31496466
97 + 31496369 = 31496466
137 + 31496329 = 31496466
149 + 31496317 = 31496466
173 + 31496293 = 31496466
257 + 31496209 = 31496466

Showing the first eight; more decompositions exist.
