Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40488, here are decompositions:
- 5 + 40483 = 40488
- 17 + 40471 = 40488
- 29 + 40459 = 40488
- 59 + 40429 = 40488
- 61 + 40427 = 40488
- 101 + 40387 = 40488
- 127 + 40361 = 40488
- 131 + 40357 = 40488
Showing the first eight; more decompositions exist.
