Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991176, here are decompositions:

5 + 991171 = 991176
29 + 991147 = 991176
47 + 991129 = 991176
97 + 991079 = 991176
103 + 991073 = 991176
107 + 991069 = 991176
113 + 991063 = 991176
139 + 991037 = 991176

Showing the first eight; more decompositions exist.
