Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18484, here are decompositions:
- 3 + 18481 = 18484
- 23 + 18461 = 18484
- 41 + 18443 = 18484
- 71 + 18413 = 18484
- 83 + 18401 = 18484
- 113 + 18371 = 18484
- 131 + 18353 = 18484
- 173 + 18311 = 18484
Showing the first eight; more decompositions exist.
