Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18932, here are decompositions:
- 13 + 18919 = 18932
- 19 + 18913 = 18932
- 73 + 18859 = 18932
- 139 + 18793 = 18932
- 241 + 18691 = 18932
- 271 + 18661 = 18932
- 349 + 18583 = 18932
- 379 + 18553 = 18932
Showing the first eight; more decompositions exist.
