Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40966, here are decompositions:
- 5 + 40961 = 40966
- 17 + 40949 = 40966
- 83 + 40883 = 40966
- 113 + 40853 = 40966
- 137 + 40829 = 40966
- 179 + 40787 = 40966
- 227 + 40739 = 40966
- 257 + 40709 = 40966
Showing the first eight; more decompositions exist.
