Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40494, here are decompositions:
- 7 + 40487 = 40494
- 11 + 40483 = 40494
- 23 + 40471 = 40494
- 61 + 40433 = 40494
- 67 + 40427 = 40494
- 71 + 40423 = 40494
- 107 + 40387 = 40494
- 137 + 40357 = 40494
Showing the first eight; more decompositions exist.
