Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86216, here are decompositions:

7 + 86209 = 86216
19 + 86197 = 86216
37 + 86179 = 86216
73 + 86143 = 86216
79 + 86137 = 86216
103 + 86113 = 86216
139 + 86077 = 86216
199 + 86017 = 86216

Showing the first eight; more decompositions exist.
