Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991076, here are decompositions:

3 + 991073 = 991076
7 + 991069 = 991076
13 + 991063 = 991076
19 + 991057 = 991076
67 + 991009 = 991076
103 + 990973 = 991076
109 + 990967 = 991076
277 + 990799 = 991076

Showing the first eight; more decompositions exist.
