Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991194, here are decompositions:

7 + 991187 = 991194
13 + 991181 = 991194
23 + 991171 = 991194
47 + 991147 = 991194
67 + 991127 = 991194
103 + 991091 = 991194
131 + 991063 = 991194
137 + 991057 = 991194

Showing the first eight; more decompositions exist.
