Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991292, here are decompositions:

19 + 991273 = 991292
31 + 991261 = 991292
163 + 991129 = 991292
223 + 991069 = 991292
229 + 991063 = 991292
283 + 991009 = 991292
331 + 990961 = 991292
619 + 990673 = 991292

Showing the first eight; more decompositions exist.
