Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8228, here are decompositions:

7 + 8221 = 8228
19 + 8209 = 8228
37 + 8191 = 8228
61 + 8167 = 8228
67 + 8161 = 8228
127 + 8101 = 8228
139 + 8089 = 8228
211 + 8017 = 8228

Showing the first eight; more decompositions exist.
