Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40960, here are decompositions:
- 11 + 40949 = 40960
- 107 + 40853 = 40960
- 113 + 40847 = 40960
- 131 + 40829 = 40960
- 137 + 40823 = 40960
- 173 + 40787 = 40960
- 197 + 40763 = 40960
- 251 + 40709 = 40960
Showing the first eight; more decompositions exist.
