Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25286, here are decompositions:
- 43 + 25243 = 25286
- 67 + 25219 = 25286
- 97 + 25189 = 25286
- 103 + 25183 = 25286
- 139 + 25147 = 25286
- 199 + 25087 = 25286
- 229 + 25057 = 25286
- 307 + 24979 = 25286
Showing the first eight; more decompositions exist.
