Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449408, here are decompositions:

5 + 31449403 = 31449408
7 + 31449401 = 31449408
31 + 31449377 = 31449408
47 + 31449361 = 31449408
149 + 31449259 = 31449408
167 + 31449241 = 31449408
229 + 31449179 = 31449408
281 + 31449127 = 31449408

Showing the first eight; more decompositions exist.
