Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484484, here are decompositions:

23 + 31484461 = 31484484
67 + 31484417 = 31484484
71 + 31484413 = 31484484
107 + 31484377 = 31484484
131 + 31484353 = 31484484
167 + 31484317 = 31484484
181 + 31484303 = 31484484
277 + 31484207 = 31484484

Showing the first eight; more decompositions exist.
