Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25902, here are decompositions:
- 13 + 25889 = 25902
- 29 + 25873 = 25902
- 53 + 25849 = 25902
- 61 + 25841 = 25902
- 83 + 25819 = 25902
- 101 + 25801 = 25902
- 103 + 25799 = 25902
- 109 + 25793 = 25902
Showing the first eight; more decompositions exist.
