Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177904, here are decompositions:
- 11 + 177893 = 177904
- 17 + 177887 = 177904
- 107 + 177797 = 177904
- 113 + 177791 = 177904
- 227 + 177677 = 177904
- 257 + 177647 = 177904
- 281 + 177623 = 177904
- 431 + 177473 = 177904
Showing the first eight; more decompositions exist.
