Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449866, here are decompositions:

13 + 31449853 = 31449866
43 + 31449823 = 31449866
109 + 31449757 = 31449866
127 + 31449739 = 31449866
193 + 31449673 = 31449866
229 + 31449637 = 31449866
277 + 31449589 = 31449866
313 + 31449553 = 31449866

Showing the first eight; more decompositions exist.
