Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18744, here are decompositions:
- 13 + 18731 = 18744
- 31 + 18713 = 18744
- 43 + 18701 = 18744
- 53 + 18691 = 18744
- 73 + 18671 = 18744
- 83 + 18661 = 18744
- 107 + 18637 = 18744
- 127 + 18617 = 18744
Showing the first eight; more decompositions exist.
