Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991316, here are decompositions:

3 + 991313 = 991316
43 + 991273 = 991316
307 + 991009 = 991316
349 + 990967 = 991316
643 + 990673 = 991316
673 + 990643 = 991316
727 + 990589 = 991316
757 + 990559 = 991316

Showing the first eight; more decompositions exist.
