Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7958, here are decompositions:

7 + 7951 = 7958
31 + 7927 = 7958
79 + 7879 = 7958
199 + 7759 = 7958
241 + 7717 = 7958
271 + 7687 = 7958
277 + 7681 = 7958
337 + 7621 = 7958

Showing the first eight; more decompositions exist.
