Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987216, here are decompositions:

5 + 987211 = 987216
7 + 987209 = 987216
17 + 987199 = 987216
23 + 987193 = 987216
73 + 987143 = 987216
89 + 987127 = 987216
127 + 987089 = 987216
137 + 987079 = 987216

Showing the first eight; more decompositions exist.
