Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549448, here are decompositions:

37 + 31549411 = 31549448
67 + 31549381 = 31549448
109 + 31549339 = 31549448
211 + 31549237 = 31549448
241 + 31549207 = 31549448
331 + 31549117 = 31549448
349 + 31549099 = 31549448
367 + 31549081 = 31549448

Showing the first eight; more decompositions exist.
