Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991274, here are decompositions:

13 + 991261 = 991274
73 + 991201 = 991274
103 + 991171 = 991274
127 + 991147 = 991274
211 + 991063 = 991274
307 + 990967 = 991274
313 + 990961 = 991274
433 + 990841 = 991274

Showing the first eight; more decompositions exist.
