Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86018, here are decompositions:

7 + 86011 = 86018
19 + 85999 = 86018
109 + 85909 = 86018
181 + 85837 = 86018
199 + 85819 = 86018
307 + 85711 = 86018
349 + 85669 = 86018
379 + 85639 = 86018

Showing the first eight; more decompositions exist.
