Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4086, here are decompositions:

7 + 4079 = 4086
13 + 4073 = 4086
29 + 4057 = 4086
37 + 4049 = 4086
59 + 4027 = 4086
67 + 4019 = 4086
73 + 4013 = 4086
79 + 4007 = 4086

Showing the first eight; more decompositions exist.
