Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41920, here are decompositions:
- 17 + 41903 = 41920
- 23 + 41897 = 41920
- 41 + 41879 = 41920
- 71 + 41849 = 41920
- 107 + 41813 = 41920
- 149 + 41771 = 41920
- 191 + 41729 = 41920
- 233 + 41687 = 41920
Showing the first eight; more decompositions exist.
