Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8258, here are decompositions:
- 37 + 8221 = 8258
- 67 + 8191 = 8258
- 79 + 8179 = 8258
- 97 + 8161 = 8258
- 157 + 8101 = 8258
- 199 + 8059 = 8258
- 241 + 8017 = 8258
- 307 + 7951 = 8258
Showing the first eight; more decompositions exist.
