Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549274, here are decompositions:

37 + 31549237 = 31549274
67 + 31549207 = 31549274
73 + 31549201 = 31549274
157 + 31549117 = 31549274
193 + 31549081 = 31549274
223 + 31549051 = 31549274
277 + 31548997 = 31549274
313 + 31548961 = 31549274

Showing the first eight; more decompositions exist.
