Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18892, here are decompositions:
- 23 + 18869 = 18892
- 53 + 18839 = 18892
- 89 + 18803 = 18892
- 149 + 18743 = 18892
- 173 + 18719 = 18892
- 179 + 18713 = 18892
- 191 + 18701 = 18892
- 353 + 18539 = 18892
Showing the first eight; more decompositions exist.
