Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549376, here are decompositions:

3 + 31549373 = 31549376
37 + 31549339 = 31549376
139 + 31549237 = 31549376
193 + 31549183 = 31549376
277 + 31549099 = 31549376
337 + 31549039 = 31549376
367 + 31549009 = 31549376
379 + 31548997 = 31549376

Showing the first eight; more decompositions exist.
