Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991974, here are decompositions:

13 + 991961 = 991974
17 + 991957 = 991974
23 + 991951 = 991974
31 + 991943 = 991974
43 + 991931 = 991974
47 + 991927 = 991974
73 + 991901 = 991974
101 + 991873 = 991974

Showing the first eight; more decompositions exist.
