Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8576, here are decompositions:

3 + 8573 = 8576
13 + 8563 = 8576
37 + 8539 = 8576
109 + 8467 = 8576
157 + 8419 = 8576
199 + 8377 = 8576
223 + 8353 = 8576
283 + 8293 = 8576

Showing the first eight; more decompositions exist.
