Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991716, here are decompositions:

13 + 991703 = 991716
23 + 991693 = 991716
53 + 991663 = 991716
73 + 991643 = 991716
83 + 991633 = 991716
97 + 991619 = 991716
109 + 991607 = 991716
113 + 991603 = 991716

Showing the first eight; more decompositions exist.
