Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40894, here are decompositions:
- 11 + 40883 = 40894
- 41 + 40853 = 40894
- 47 + 40847 = 40894
- 53 + 40841 = 40894
- 71 + 40823 = 40894
- 107 + 40787 = 40894
- 131 + 40763 = 40894
- 197 + 40697 = 40894
Showing the first eight; more decompositions exist.
