Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549098, here are decompositions:

11 + 31549087 = 31549098
17 + 31549081 = 31549098
47 + 31549051 = 31549098
59 + 31549039 = 31549098
79 + 31549019 = 31549098
89 + 31549009 = 31549098
101 + 31548997 = 31549098
137 + 31548961 = 31549098

Showing the first eight; more decompositions exist.
