Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494916, here are decompositions:

29 + 31494887 = 31494916
107 + 31494809 = 31494916
149 + 31494767 = 31494916
179 + 31494737 = 31494916
227 + 31494689 = 31494916
419 + 31494497 = 31494916
449 + 31494467 = 31494916
569 + 31494347 = 31494916

Showing the first eight; more decompositions exist.
