Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87216, here are decompositions:

5 + 87211 = 87216
29 + 87187 = 87216
37 + 87179 = 87216
67 + 87149 = 87216
83 + 87133 = 87216
97 + 87119 = 87216
109 + 87107 = 87216
113 + 87103 = 87216

Showing the first eight; more decompositions exist.
