Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534366, here are decompositions:

23 + 31534343 = 31534366
167 + 31534199 = 31534366
179 + 31534187 = 31534366
197 + 31534169 = 31534366
263 + 31534103 = 31534366
293 + 31534073 = 31534366
443 + 31533923 = 31534366
593 + 31533773 = 31534366

Showing the first eight; more decompositions exist.
