Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17472, here are decompositions:
- 5 + 17467 = 17472
- 23 + 17449 = 17472
- 29 + 17443 = 17472
- 41 + 17431 = 17472
- 53 + 17419 = 17472
- 71 + 17401 = 17472
- 79 + 17393 = 17472
- 83 + 17389 = 17472
Showing the first eight; more decompositions exist.
