Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991058, here are decompositions:

31 + 991027 = 991058
97 + 990961 = 991058
421 + 990637 = 991058
499 + 990559 = 991058
547 + 990511 = 991058
571 + 990487 = 991058
661 + 990397 = 991058
709 + 990349 = 991058

Showing the first eight; more decompositions exist.
