Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8422, here are decompositions:

3 + 8419 = 8422
53 + 8369 = 8422
59 + 8363 = 8422
131 + 8291 = 8422
149 + 8273 = 8422
179 + 8243 = 8422
191 + 8231 = 8422
251 + 8171 = 8422

Showing the first eight; more decompositions exist.
