Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549026, here are decompositions:

7 + 31549019 = 31549026
17 + 31549009 = 31549026
29 + 31548997 = 31549026
43 + 31548983 = 31549026
73 + 31548953 = 31549026
263 + 31548763 = 31549026
269 + 31548757 = 31549026
277 + 31548749 = 31549026

Showing the first eight; more decompositions exist.
