Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86820, here are decompositions:

7 + 86813 = 86820
37 + 86783 = 86820
53 + 86767 = 86820
67 + 86753 = 86820
101 + 86719 = 86820
109 + 86711 = 86820
127 + 86693 = 86820
131 + 86689 = 86820

Showing the first eight; more decompositions exist.
