Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18708, here are decompositions:
- 7 + 18701 = 18708
- 17 + 18691 = 18708
- 29 + 18679 = 18708
- 37 + 18671 = 18708
- 47 + 18661 = 18708
- 71 + 18637 = 18708
- 167 + 18541 = 18708
- 191 + 18517 = 18708
Showing the first eight; more decompositions exist.
