Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449916, here are decompositions:

149 + 31449767 = 31449916
227 + 31449689 = 31449916
269 + 31449647 = 31449916
347 + 31449569 = 31449916
359 + 31449557 = 31449916
389 + 31449527 = 31449916
467 + 31449449 = 31449916
557 + 31449359 = 31449916

Showing the first eight; more decompositions exist.
