Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18850, here are decompositions:
- 11 + 18839 = 18850
- 47 + 18803 = 18850
- 53 + 18797 = 18850
- 101 + 18749 = 18850
- 107 + 18743 = 18850
- 131 + 18719 = 18850
- 137 + 18713 = 18850
- 149 + 18701 = 18850
Showing the first eight; more decompositions exist.
