Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40216, here are decompositions:

3 + 40213 = 40216
23 + 40193 = 40216
47 + 40169 = 40216
53 + 40163 = 40216
89 + 40127 = 40216
179 + 40037 = 40216
227 + 39989 = 40216
233 + 39983 = 40216

Showing the first eight; more decompositions exist.
