Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8512, here are decompositions:

11 + 8501 = 8512
83 + 8429 = 8512
89 + 8423 = 8512
149 + 8363 = 8512
239 + 8273 = 8512
269 + 8243 = 8512
281 + 8231 = 8512
293 + 8219 = 8512

Showing the first eight; more decompositions exist.
