Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971942, here are decompositions:

3 + 971939 = 971942
43 + 971899 = 971942
79 + 971863 = 971942
109 + 971833 = 971942
229 + 971713 = 971942
373 + 971569 = 971942
379 + 971563 = 971942
421 + 971521 = 971942

Showing the first eight; more decompositions exist.
