Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91258, here are decompositions:
- 5 + 91253 = 91258
- 29 + 91229 = 91258
- 59 + 91199 = 91258
- 107 + 91151 = 91258
- 131 + 91127 = 91258
- 137 + 91121 = 91258
- 179 + 91079 = 91258
- 239 + 91019 = 91258
Showing the first eight; more decompositions exist.
