Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177436, here are decompositions:
- 3 + 177433 = 177436
- 5 + 177431 = 177436
- 53 + 177383 = 177436
- 89 + 177347 = 177436
- 113 + 177323 = 177436
- 167 + 177269 = 177436
- 179 + 177257 = 177436
- 197 + 177239 = 177436
Showing the first eight; more decompositions exist.
