Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496516, here are decompositions:

67 + 31496449 = 31496516
97 + 31496419 = 31496516
127 + 31496389 = 31496516
199 + 31496317 = 31496516
223 + 31496293 = 31496516
307 + 31496209 = 31496516
397 + 31496119 = 31496516
433 + 31496083 = 31496516

Showing the first eight; more decompositions exist.
