Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18532, here are decompositions:
- 11 + 18521 = 18532
- 29 + 18503 = 18532
- 71 + 18461 = 18532
- 89 + 18443 = 18532
- 131 + 18401 = 18532
- 179 + 18353 = 18532
- 191 + 18341 = 18532
- 263 + 18269 = 18532
Showing the first eight; more decompositions exist.
