Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991268, here are decompositions:

7 + 991261 = 991268
67 + 991201 = 991268
97 + 991171 = 991268
139 + 991129 = 991268
199 + 991069 = 991268
211 + 991057 = 991268
241 + 991027 = 991268
307 + 990961 = 991268

Showing the first eight; more decompositions exist.
