Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991934, here are decompositions:

3 + 991931 = 991934
7 + 991927 = 991934
61 + 991873 = 991934
67 + 991867 = 991934
157 + 991777 = 991934
193 + 991741 = 991934
211 + 991723 = 991934
241 + 991693 = 991934

Showing the first eight; more decompositions exist.
