Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41808, here are decompositions:
- 7 + 41801 = 41808
- 31 + 41777 = 41808
- 37 + 41771 = 41808
- 47 + 41761 = 41808
- 71 + 41737 = 41808
- 79 + 41729 = 41808
- 89 + 41719 = 41808
- 127 + 41681 = 41808
Showing the first eight; more decompositions exist.
