Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40958, here are decompositions:
- 19 + 40939 = 40958
- 31 + 40927 = 40958
- 61 + 40897 = 40958
- 79 + 40879 = 40958
- 109 + 40849 = 40958
- 139 + 40819 = 40958
- 157 + 40801 = 40958
- 199 + 40759 = 40958
Showing the first eight; more decompositions exist.
