Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18876, here are decompositions:
- 7 + 18869 = 18876
- 17 + 18859 = 18876
- 37 + 18839 = 18876
- 73 + 18803 = 18876
- 79 + 18797 = 18876
- 83 + 18793 = 18876
- 89 + 18787 = 18876
- 103 + 18773 = 18876
Showing the first eight; more decompositions exist.
