Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10258, here are decompositions:
- 5 + 10253 = 10258
- 11 + 10247 = 10258
- 47 + 10211 = 10258
- 89 + 10169 = 10258
- 107 + 10151 = 10258
- 167 + 10091 = 10258
- 179 + 10079 = 10258
- 191 + 10067 = 10258
Showing the first eight; more decompositions exist.
