Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484214, here are decompositions:

5 + 31484209 = 31484214
7 + 31484207 = 31484214
11 + 31484203 = 31484214
37 + 31484177 = 31484214
53 + 31484161 = 31484214
71 + 31484143 = 31484214
233 + 31483981 = 31484214
257 + 31483957 = 31484214

Showing the first eight; more decompositions exist.
