Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40398, here are decompositions:
- 11 + 40387 = 40398
- 37 + 40361 = 40398
- 41 + 40357 = 40398
- 47 + 40351 = 40398
- 109 + 40289 = 40398
- 157 + 40241 = 40398
- 167 + 40231 = 40398
- 229 + 40169 = 40398
Showing the first eight; more decompositions exist.
