Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8432, here are decompositions:

3 + 8429 = 8432
13 + 8419 = 8432
43 + 8389 = 8432
79 + 8353 = 8432
103 + 8329 = 8432
139 + 8293 = 8432
163 + 8269 = 8432
199 + 8233 = 8432

Showing the first eight; more decompositions exist.
