Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449676, here are decompositions:

3 + 31449673 = 31449676
29 + 31449647 = 31449676
47 + 31449629 = 31449676
107 + 31449569 = 31449676
149 + 31449527 = 31449676
197 + 31449479 = 31449676
227 + 31449449 = 31449676
317 + 31449359 = 31449676

Showing the first eight; more decompositions exist.
