Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991046, here are decompositions:

3 + 991043 = 991046
19 + 991027 = 991046
37 + 991009 = 991046
73 + 990973 = 991046
79 + 990967 = 991046
157 + 990889 = 991046
313 + 990733 = 991046
373 + 990673 = 991046

Showing the first eight; more decompositions exist.
