Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17490, here are decompositions:
- 7 + 17483 = 17490
- 13 + 17477 = 17490
- 19 + 17471 = 17490
- 23 + 17467 = 17490
- 41 + 17449 = 17490
- 47 + 17443 = 17490
- 59 + 17431 = 17490
- 71 + 17419 = 17490
Showing the first eight; more decompositions exist.
