Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991326, here are decompositions:

13 + 991313 = 991326
53 + 991273 = 991326
97 + 991229 = 991326
103 + 991223 = 991326
109 + 991217 = 991326
139 + 991187 = 991326
179 + 991147 = 991326
197 + 991129 = 991326

Showing the first eight; more decompositions exist.
