Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40738, here are decompositions:
- 29 + 40709 = 40738
- 41 + 40697 = 40738
- 101 + 40637 = 40738
- 179 + 40559 = 40738
- 239 + 40499 = 40738
- 251 + 40487 = 40738
- 311 + 40427 = 40738
- 449 + 40289 = 40738
Showing the first eight; more decompositions exist.
