Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8000, here are decompositions:

7 + 7993 = 8000
37 + 7963 = 8000
67 + 7933 = 8000
73 + 7927 = 8000
127 + 7873 = 8000
211 + 7789 = 8000
241 + 7759 = 8000
277 + 7723 = 8000

Showing the first eight; more decompositions exist.
