Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71858, here are decompositions:
- 37 + 71821 = 71858
- 97 + 71761 = 71858
- 139 + 71719 = 71858
- 151 + 71707 = 71858
- 211 + 71647 = 71858
- 307 + 71551 = 71858
- 331 + 71527 = 71858
- 379 + 71479 = 71858
Showing the first eight; more decompositions exist.
