Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449108, here are decompositions:

37 + 31449071 = 31449108
71 + 31449037 = 31449108
79 + 31449029 = 31449108
199 + 31448909 = 31449108
211 + 31448897 = 31449108
269 + 31448839 = 31449108
367 + 31448741 = 31449108
389 + 31448719 = 31449108

Showing the first eight; more decompositions exist.
