Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8006, here are decompositions:

13 + 7993 = 8006
43 + 7963 = 8006
73 + 7933 = 8006
79 + 7927 = 8006
127 + 7879 = 8006
139 + 7867 = 8006
283 + 7723 = 8006
307 + 7699 = 8006

Showing the first eight; more decompositions exist.
