Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13902, here are decompositions:
- 19 + 13883 = 13902
- 23 + 13879 = 13902
- 29 + 13873 = 13902
- 43 + 13859 = 13902
- 61 + 13841 = 13902
- 71 + 13831 = 13902
- 73 + 13829 = 13902
- 103 + 13799 = 13902
Showing the first eight; more decompositions exist.
