Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40086, here are decompositions:

23 + 40063 = 40086
47 + 40039 = 40086
73 + 40013 = 40086
97 + 39989 = 40086
103 + 39983 = 40086
107 + 39979 = 40086
149 + 39937 = 40086
157 + 39929 = 40086

Showing the first eight; more decompositions exist.
