Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484304, here are decompositions:

23 + 31484281 = 31484304
37 + 31484267 = 31484304
67 + 31484237 = 31484304
97 + 31484207 = 31484304
101 + 31484203 = 31484304
127 + 31484177 = 31484304
211 + 31484093 = 31484304
223 + 31484081 = 31484304

Showing the first eight; more decompositions exist.
