Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18450, here are decompositions:
- 7 + 18443 = 18450
- 11 + 18439 = 18450
- 17 + 18433 = 18450
- 23 + 18427 = 18450
- 37 + 18413 = 18450
- 53 + 18397 = 18450
- 71 + 18379 = 18450
- 79 + 18371 = 18450
Showing the first eight; more decompositions exist.
