Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18826, here are decompositions:
- 23 + 18803 = 18826
- 29 + 18797 = 18826
- 53 + 18773 = 18826
- 83 + 18743 = 18826
- 107 + 18719 = 18826
- 113 + 18713 = 18826
- 233 + 18593 = 18826
- 239 + 18587 = 18826
Showing the first eight; more decompositions exist.
