Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991314, here are decompositions:

41 + 991273 = 991314
53 + 991261 = 991314
97 + 991217 = 991314
113 + 991201 = 991314
127 + 991187 = 991314
167 + 991147 = 991314
223 + 991091 = 991314
241 + 991073 = 991314

Showing the first eight; more decompositions exist.
