Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494706, here are decompositions:

17 + 31494689 = 31494706
197 + 31494509 = 31494706
227 + 31494479 = 31494706
239 + 31494467 = 31494706
263 + 31494443 = 31494706
317 + 31494389 = 31494706
359 + 31494347 = 31494706
443 + 31494263 = 31494706

Showing the first eight; more decompositions exist.
