Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8456, here are decompositions:
- 13 + 8443 = 8456
- 37 + 8419 = 8456
- 67 + 8389 = 8456
- 79 + 8377 = 8456
- 103 + 8353 = 8456
- 127 + 8329 = 8456
- 139 + 8317 = 8456
- 163 + 8293 = 8456
Showing the first eight; more decompositions exist.
