Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991954, here are decompositions:

3 + 991951 = 991954
11 + 991943 = 991954
23 + 991931 = 991954
53 + 991901 = 991954
71 + 991883 = 991954
83 + 991871 = 991954
137 + 991817 = 991954
251 + 991703 = 991954

Showing the first eight; more decompositions exist.
