Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991064, here are decompositions:

7 + 991057 = 991064
37 + 991027 = 991064
97 + 990967 = 991064
103 + 990961 = 991064
223 + 990841 = 991064
331 + 990733 = 991064
421 + 990643 = 991064
433 + 990631 = 991064

Showing the first eight; more decompositions exist.
