Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8528, here are decompositions:

7 + 8521 = 8528
61 + 8467 = 8528
67 + 8461 = 8528
97 + 8431 = 8528
109 + 8419 = 8528
139 + 8389 = 8528
151 + 8377 = 8528
199 + 8329 = 8528

Showing the first eight; more decompositions exist.
