Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494412, here are decompositions:

11 + 31494401 = 31494412
23 + 31494389 = 31494412
149 + 31494263 = 31494412
233 + 31494179 = 31494412
251 + 31494161 = 31494412
269 + 31494143 = 31494412
293 + 31494119 = 31494412
359 + 31494053 = 31494412

Showing the first eight; more decompositions exist.
