Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991794, here are decompositions:

17 + 991777 = 991794
43 + 991751 = 991794
53 + 991741 = 991794
61 + 991733 = 991794
71 + 991723 = 991794
101 + 991693 = 991794
131 + 991663 = 991794
151 + 991643 = 991794

Showing the first eight; more decompositions exist.
