Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40660, here are decompositions:
- 23 + 40637 = 40660
- 83 + 40577 = 40660
- 101 + 40559 = 40660
- 131 + 40529 = 40660
- 167 + 40493 = 40660
- 173 + 40487 = 40660
- 227 + 40433 = 40660
- 233 + 40427 = 40660
Showing the first eight; more decompositions exist.
