Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991052, here are decompositions:

43 + 991009 = 991052
79 + 990973 = 991052
163 + 990889 = 991052
211 + 990841 = 991052
379 + 990673 = 991052
409 + 990643 = 991052
421 + 990631 = 991052
463 + 990589 = 991052

Showing the first eight; more decompositions exist.
