Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82086, here are decompositions:

13 + 82073 = 82086
19 + 82067 = 82086
47 + 82039 = 82086
73 + 82013 = 82086
79 + 82007 = 82086
83 + 82003 = 82086
113 + 81973 = 82086
149 + 81937 = 82086

Showing the first eight; more decompositions exist.
