Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8238, here are decompositions:

5 + 8233 = 8238
7 + 8231 = 8238
17 + 8221 = 8238
19 + 8219 = 8238
29 + 8209 = 8238
47 + 8191 = 8238
59 + 8179 = 8238
67 + 8171 = 8238

Showing the first eight; more decompositions exist.
