Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8534, here are decompositions:

7 + 8527 = 8534
13 + 8521 = 8534
67 + 8467 = 8534
73 + 8461 = 8534
103 + 8431 = 8534
157 + 8377 = 8534
181 + 8353 = 8534
223 + 8311 = 8534

Showing the first eight; more decompositions exist.
