Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449416, here are decompositions:

7 + 31449409 = 31449416
13 + 31449403 = 31449416
43 + 31449373 = 31449416
127 + 31449289 = 31449416
157 + 31449259 = 31449416
373 + 31449043 = 31449416
379 + 31449037 = 31449416
577 + 31448839 = 31449416

Showing the first eight; more decompositions exist.
