Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86658, here are decompositions:

29 + 86629 = 86658
31 + 86627 = 86658
59 + 86599 = 86658
71 + 86587 = 86658
79 + 86579 = 86658
97 + 86561 = 86658
127 + 86531 = 86658
149 + 86509 = 86658

Showing the first eight; more decompositions exist.
