Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7994, here are decompositions:

31 + 7963 = 7994
43 + 7951 = 7994
61 + 7933 = 7994
67 + 7927 = 7994
127 + 7867 = 7994
241 + 7753 = 7994
271 + 7723 = 7994
277 + 7717 = 7994

Showing the first eight; more decompositions exist.
