Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71158, here are decompositions:
- 5 + 71153 = 71158
- 11 + 71147 = 71158
- 29 + 71129 = 71158
- 89 + 71069 = 71158
- 167 + 70991 = 71158
- 179 + 70979 = 71158
- 239 + 70919 = 71158
- 257 + 70901 = 71158
Showing the first eight; more decompositions exist.
