Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484694, here are decompositions:

47 + 31484647 = 31484694
67 + 31484627 = 31484694
151 + 31484543 = 31484694
181 + 31484513 = 31484694
191 + 31484503 = 31484694
233 + 31484461 = 31484694
277 + 31484417 = 31484694
281 + 31484413 = 31484694

Showing the first eight; more decompositions exist.
