Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40690, here are decompositions:
- 53 + 40637 = 40690
- 107 + 40583 = 40690
- 113 + 40577 = 40690
- 131 + 40559 = 40690
- 191 + 40499 = 40690
- 197 + 40493 = 40690
- 257 + 40433 = 40690
- 263 + 40427 = 40690
Showing the first eight; more decompositions exist.
