Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18526, here are decompositions:
- 3 + 18523 = 18526
- 5 + 18521 = 18526
- 23 + 18503 = 18526
- 83 + 18443 = 18526
- 113 + 18413 = 18526
- 173 + 18353 = 18526
- 197 + 18329 = 18526
- 239 + 18287 = 18526
Showing the first eight; more decompositions exist.
