Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449966, here are decompositions:

29 + 31449937 = 31449966
43 + 31449923 = 31449966
113 + 31449853 = 31449966
199 + 31449767 = 31449966
227 + 31449739 = 31449966
269 + 31449697 = 31449966
277 + 31449689 = 31449966
293 + 31449673 = 31449966

Showing the first eight; more decompositions exist.
