Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71558, here are decompositions:
- 7 + 71551 = 71558
- 31 + 71527 = 71558
- 79 + 71479 = 71558
- 139 + 71419 = 71558
- 199 + 71359 = 71558
- 211 + 71347 = 71558
- 229 + 71329 = 71558
- 241 + 71317 = 71558
Showing the first eight; more decompositions exist.
