Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8500, here are decompositions:

53 + 8447 = 8500
71 + 8429 = 8500
113 + 8387 = 8500
131 + 8369 = 8500
137 + 8363 = 8500
227 + 8273 = 8500
257 + 8243 = 8500
263 + 8237 = 8500

Showing the first eight; more decompositions exist.
