Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18760, here are decompositions:
- 3 + 18757 = 18760
- 11 + 18749 = 18760
- 17 + 18743 = 18760
- 29 + 18731 = 18760
- 41 + 18719 = 18760
- 47 + 18713 = 18760
- 59 + 18701 = 18760
- 89 + 18671 = 18760
Showing the first eight; more decompositions exist.
