Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18486, here are decompositions:
- 5 + 18481 = 18486
- 29 + 18457 = 18486
- 43 + 18443 = 18486
- 47 + 18439 = 18486
- 53 + 18433 = 18486
- 59 + 18427 = 18486
- 73 + 18413 = 18486
- 89 + 18397 = 18486
Showing the first eight; more decompositions exist.
