Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18834, here are decompositions:
- 31 + 18803 = 18834
- 37 + 18797 = 18834
- 41 + 18793 = 18834
- 47 + 18787 = 18834
- 61 + 18773 = 18834
- 103 + 18731 = 18834
- 163 + 18671 = 18834
- 173 + 18661 = 18834
Showing the first eight; more decompositions exist.
