Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177748, here are decompositions:
- 5 + 177743 = 177748
- 71 + 177677 = 177748
- 101 + 177647 = 177748
- 281 + 177467 = 177748
- 317 + 177431 = 177748
- 401 + 177347 = 177748
- 479 + 177269 = 177748
- 491 + 177257 = 177748
Showing the first eight; more decompositions exist.
