Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25982, here are decompositions:
- 13 + 25969 = 25982
- 31 + 25951 = 25982
- 43 + 25939 = 25982
- 79 + 25903 = 25982
- 109 + 25873 = 25982
- 163 + 25819 = 25982
- 181 + 25801 = 25982
- 211 + 25771 = 25982
Showing the first eight; more decompositions exist.
