Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89216, here are decompositions:

3 + 89213 = 89216
7 + 89209 = 89216
13 + 89203 = 89216
79 + 89137 = 89216
97 + 89119 = 89216
103 + 89113 = 89216
109 + 89107 = 89216
199 + 89017 = 89216

Showing the first eight; more decompositions exist.
