Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8472, here are decompositions:
- 5 + 8467 = 8472
- 11 + 8461 = 8472
- 29 + 8443 = 8472
- 41 + 8431 = 8472
- 43 + 8429 = 8472
- 53 + 8419 = 8472
- 83 + 8389 = 8472
- 103 + 8369 = 8472
Showing the first eight; more decompositions exist.
