Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991754, here are decompositions:

3 + 991751 = 991754
13 + 991741 = 991754
31 + 991723 = 991754
37 + 991717 = 991754
61 + 991693 = 991754
103 + 991651 = 991754
151 + 991603 = 991754
223 + 991531 = 991754

Showing the first eight; more decompositions exist.
