Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177886, here are decompositions:
- 3 + 177883 = 177886
- 47 + 177839 = 177886
- 89 + 177797 = 177886
- 239 + 177647 = 177886
- 263 + 177623 = 177886
- 347 + 177539 = 177886
- 353 + 177533 = 177886
- 419 + 177467 = 177886
Showing the first eight; more decompositions exist.
