Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549124, here are decompositions:

7 + 31549117 = 31549124
37 + 31549087 = 31549124
43 + 31549081 = 31549124
73 + 31549051 = 31549124
127 + 31548997 = 31549124
163 + 31548961 = 31549124
307 + 31548817 = 31549124
367 + 31548757 = 31549124

Showing the first eight; more decompositions exist.
