Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18882, here are decompositions:
- 13 + 18869 = 18882
- 23 + 18859 = 18882
- 43 + 18839 = 18882
- 79 + 18803 = 18882
- 89 + 18793 = 18882
- 109 + 18773 = 18882
- 139 + 18743 = 18882
- 151 + 18731 = 18882
Showing the first eight; more decompositions exist.
