Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549636, here are decompositions:

29 + 31549607 = 31549636
47 + 31549589 = 31549636
89 + 31549547 = 31549636
137 + 31549499 = 31549636
197 + 31549439 = 31549636
233 + 31549403 = 31549636
263 + 31549373 = 31549636
359 + 31549277 = 31549636

Showing the first eight; more decompositions exist.
