Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177688, here are decompositions:
- 11 + 177677 = 177688
- 41 + 177647 = 177688
- 149 + 177539 = 177688
- 257 + 177431 = 177688
- 419 + 177269 = 177688
- 431 + 177257 = 177688
- 449 + 177239 = 177688
- 479 + 177209 = 177688
Showing the first eight; more decompositions exist.
