Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658, here are decompositions:

11 + 8647 = 8658
17 + 8641 = 8658
29 + 8629 = 8658
31 + 8627 = 8658
59 + 8599 = 8658
61 + 8597 = 8658
131 + 8527 = 8658
137 + 8521 = 8658

Showing the first eight; more decompositions exist.
