Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549184, here are decompositions:

3 + 31549181 = 31549184
67 + 31549117 = 31549184
97 + 31549087 = 31549184
103 + 31549081 = 31549184
223 + 31548961 = 31549184
313 + 31548871 = 31549184
367 + 31548817 = 31549184
421 + 31548763 = 31549184

Showing the first eight; more decompositions exist.
