Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484146, here are decompositions:

3 + 31484143 = 31484146
17 + 31484129 = 31484146
53 + 31484093 = 31484146
167 + 31483979 = 31484146
227 + 31483919 = 31484146
233 + 31483913 = 31484146
257 + 31483889 = 31484146
263 + 31483883 = 31484146

Showing the first eight; more decompositions exist.
