Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86616, here are decompositions:

17 + 86599 = 86616
29 + 86587 = 86616
37 + 86579 = 86616
43 + 86573 = 86616
83 + 86533 = 86616
107 + 86509 = 86616
139 + 86477 = 86616
149 + 86467 = 86616

Showing the first eight; more decompositions exist.
