Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18946, here are decompositions:
- 29 + 18917 = 18946
- 47 + 18899 = 18946
- 107 + 18839 = 18946
- 149 + 18797 = 18946
- 173 + 18773 = 18946
- 197 + 18749 = 18946
- 227 + 18719 = 18946
- 233 + 18713 = 18946
Showing the first eight; more decompositions exist.
