Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18376, here are decompositions:
- 5 + 18371 = 18376
- 23 + 18353 = 18376
- 47 + 18329 = 18376
- 89 + 18287 = 18376
- 107 + 18269 = 18376
- 227 + 18149 = 18376
- 233 + 18143 = 18376
- 257 + 18119 = 18376
Showing the first eight; more decompositions exist.
