Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177558, here are decompositions:
- 5 + 177553 = 177558
- 19 + 177539 = 177558
- 47 + 177511 = 177558
- 71 + 177487 = 177558
- 127 + 177431 = 177558
- 131 + 177427 = 177558
- 137 + 177421 = 177558
- 149 + 177409 = 177558
Showing the first eight; more decompositions exist.
