Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77158, here are decompositions:
- 5 + 77153 = 77158
- 17 + 77141 = 77158
- 89 + 77069 = 77158
- 167 + 76991 = 77158
- 197 + 76961 = 77158
- 239 + 76919 = 77158
- 251 + 76907 = 77158
- 311 + 76847 = 77158
Showing the first eight; more decompositions exist.
