Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971940, here are decompositions:

7 + 971933 = 971940
19 + 971921 = 971940
23 + 971917 = 971940
37 + 971903 = 971940
41 + 971899 = 971940
83 + 971857 = 971940
89 + 971851 = 971940
107 + 971833 = 971940

Showing the first eight; more decompositions exist.
