Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7976, here are decompositions:

13 + 7963 = 7976
43 + 7933 = 7976
97 + 7879 = 7976
103 + 7873 = 7976
109 + 7867 = 7976
223 + 7753 = 7976
277 + 7699 = 7976
307 + 7669 = 7976

Showing the first eight; more decompositions exist.
