Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991834, here are decompositions:

17 + 991817 = 991834
23 + 991811 = 991834
83 + 991751 = 991834
101 + 991733 = 991834
131 + 991703 = 991834
191 + 991643 = 991834
227 + 991607 = 991834
293 + 991541 = 991834

Showing the first eight; more decompositions exist.
