Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28086, here are decompositions:

5 + 28081 = 28086
17 + 28069 = 28086
29 + 28057 = 28086
59 + 28027 = 28086
67 + 28019 = 28086
89 + 27997 = 28086
103 + 27983 = 28086
139 + 27947 = 28086

Showing the first eight; more decompositions exist.
