Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18502, here are decompositions:
- 41 + 18461 = 18502
- 59 + 18443 = 18502
- 89 + 18413 = 18502
- 101 + 18401 = 18502
- 131 + 18371 = 18502
- 149 + 18353 = 18502
- 173 + 18329 = 18502
- 191 + 18311 = 18502
Showing the first eight; more decompositions exist.
