Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25980, here are decompositions:
- 11 + 25969 = 25980
- 29 + 25951 = 25980
- 37 + 25943 = 25980
- 41 + 25939 = 25980
- 47 + 25933 = 25980
- 61 + 25919 = 25980
- 67 + 25913 = 25980
- 107 + 25873 = 25980
Showing the first eight; more decompositions exist.
