Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25166, here are decompositions:
- 3 + 25163 = 25166
- 13 + 25153 = 25166
- 19 + 25147 = 25166
- 79 + 25087 = 25166
- 109 + 25057 = 25166
- 199 + 24967 = 25166
- 223 + 24943 = 25166
- 277 + 24889 = 25166
Showing the first eight; more decompositions exist.
