Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86220, here are decompositions:

11 + 86209 = 86220
19 + 86201 = 86220
23 + 86197 = 86220
37 + 86183 = 86220
41 + 86179 = 86220
59 + 86161 = 86220
83 + 86137 = 86220
89 + 86131 = 86220

Showing the first eight; more decompositions exist.
