Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8412, here are decompositions:
- 23 + 8389 = 8412
- 43 + 8369 = 8412
- 59 + 8353 = 8412
- 83 + 8329 = 8412
- 101 + 8311 = 8412
- 139 + 8273 = 8412
- 149 + 8263 = 8412
- 179 + 8233 = 8412
Showing the first eight; more decompositions exist.
