Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991792, here are decompositions:

41 + 991751 = 991792
59 + 991733 = 991792
89 + 991703 = 991792
149 + 991643 = 991792
173 + 991619 = 991792
251 + 991541 = 991792
281 + 991511 = 991792
293 + 991499 = 991792

Showing the first eight; more decompositions exist.
