Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177588, here are decompositions:
- 101 + 177487 = 177588
- 107 + 177481 = 177588
- 157 + 177431 = 177588
- 167 + 177421 = 177588
- 179 + 177409 = 177588
- 241 + 177347 = 177588
- 251 + 177337 = 177588
- 269 + 177319 = 177588
Showing the first eight; more decompositions exist.
