Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991796, here are decompositions:

19 + 991777 = 991796
73 + 991723 = 991796
79 + 991717 = 991796
103 + 991693 = 991796
163 + 991633 = 991796
193 + 991603 = 991796
229 + 991567 = 991796
313 + 991483 = 991796

Showing the first eight; more decompositions exist.
