Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991896, here are decompositions:

7 + 991889 = 991896
13 + 991883 = 991896
23 + 991873 = 991896
29 + 991867 = 991896
79 + 991817 = 991896
163 + 991733 = 991896
173 + 991723 = 991896
179 + 991717 = 991896

Showing the first eight; more decompositions exist.
