Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86318, here are decompositions:

7 + 86311 = 86318
31 + 86287 = 86318
61 + 86257 = 86318
79 + 86239 = 86318
109 + 86209 = 86318
139 + 86179 = 86318
157 + 86161 = 86318
181 + 86137 = 86318

Showing the first eight; more decompositions exist.
