Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18498, here are decompositions:
- 5 + 18493 = 18498
- 17 + 18481 = 18498
- 37 + 18461 = 18498
- 41 + 18457 = 18498
- 47 + 18451 = 18498
- 59 + 18439 = 18498
- 71 + 18427 = 18498
- 97 + 18401 = 18498
Showing the first eight; more decompositions exist.
