Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484536, here are decompositions:

3 + 31484533 = 31484536
23 + 31484513 = 31484536
173 + 31484363 = 31484536
197 + 31484339 = 31484536
233 + 31484303 = 31484536
269 + 31484267 = 31484536
359 + 31484177 = 31484536
443 + 31484093 = 31484536

Showing the first eight; more decompositions exist.
