Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25838, here are decompositions:
- 19 + 25819 = 25838
- 37 + 25801 = 25838
- 67 + 25771 = 25838
- 79 + 25759 = 25838
- 97 + 25741 = 25838
- 181 + 25657 = 25838
- 199 + 25639 = 25838
- 229 + 25609 = 25838
Showing the first eight; more decompositions exist.
