Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549094, here are decompositions:

7 + 31549087 = 31549094
13 + 31549081 = 31549094
43 + 31549051 = 31549094
97 + 31548997 = 31549094
223 + 31548871 = 31549094
271 + 31548823 = 31549094
277 + 31548817 = 31549094
331 + 31548763 = 31549094

Showing the first eight; more decompositions exist.
