Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8470, here are decompositions:

3 + 8467 = 8470
23 + 8447 = 8470
41 + 8429 = 8470
47 + 8423 = 8470
83 + 8387 = 8470
101 + 8369 = 8470
107 + 8363 = 8470
173 + 8297 = 8470

Showing the first eight; more decompositions exist.
