Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991746, here are decompositions:

5 + 991741 = 991746
13 + 991733 = 991746
23 + 991723 = 991746
29 + 991717 = 991746
43 + 991703 = 991746
53 + 991693 = 991746
83 + 991663 = 991746
103 + 991643 = 991746

Showing the first eight; more decompositions exist.
