Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449066, here are decompositions:

13 + 31449053 = 31449066
23 + 31449043 = 31449066
29 + 31449037 = 31449066
37 + 31449029 = 31449066
79 + 31448987 = 31449066
157 + 31448909 = 31449066
163 + 31448903 = 31449066
167 + 31448899 = 31449066

Showing the first eight; more decompositions exist.
