Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25138, here are decompositions:
- 11 + 25127 = 25138
- 17 + 25121 = 25138
- 41 + 25097 = 25138
- 101 + 25037 = 25138
- 107 + 25031 = 25138
- 149 + 24989 = 25138
- 167 + 24971 = 25138
- 317 + 24821 = 25138
Showing the first eight; more decompositions exist.
