Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993906, here are decompositions:

13 + 993893 = 993906
19 + 993887 = 993906
37 + 993869 = 993906
79 + 993827 = 993906
83 + 993823 = 993906
113 + 993793 = 993906
127 + 993779 = 993906
223 + 993683 = 993906

Showing the first eight; more decompositions exist.
