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.
