Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549716, here are decompositions:

53 + 31549663 = 31549716
67 + 31549649 = 31549716
109 + 31549607 = 31549716
127 + 31549589 = 31549716
137 + 31549579 = 31549716
277 + 31549439 = 31549716
313 + 31549403 = 31549716
379 + 31549337 = 31549716

Showing the first eight; more decompositions exist.
