Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449846, here are decompositions:

23 + 31449823 = 31449846
79 + 31449767 = 31449846
89 + 31449757 = 31449846
107 + 31449739 = 31449846
149 + 31449697 = 31449846
157 + 31449689 = 31449846
167 + 31449679 = 31449846
173 + 31449673 = 31449846

Showing the first eight; more decompositions exist.
