Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8510, here are decompositions:

43 + 8467 = 8510
67 + 8443 = 8510
79 + 8431 = 8510
157 + 8353 = 8510
181 + 8329 = 8510
193 + 8317 = 8510
199 + 8311 = 8510
223 + 8287 = 8510

Showing the first eight; more decompositions exist.
