Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991932, here are decompositions:

5 + 991927 = 991932
23 + 991909 = 991932
31 + 991901 = 991932
43 + 991889 = 991932
59 + 991873 = 991932
61 + 991871 = 991932
181 + 991751 = 991932
191 + 991741 = 991932

Showing the first eight; more decompositions exist.
