Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449266, here are decompositions:

3 + 31449263 = 31449266
7 + 31449259 = 31449266
19 + 31449247 = 31449266
103 + 31449163 = 31449266
139 + 31449127 = 31449266
223 + 31449043 = 31449266
229 + 31449037 = 31449266
367 + 31448899 = 31449266

Showing the first eight; more decompositions exist.
