Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177806, here are decompositions:
- 19 + 177787 = 177806
- 43 + 177763 = 177806
- 67 + 177739 = 177806
- 127 + 177679 = 177806
- 313 + 177493 = 177806
- 373 + 177433 = 177806
- 379 + 177427 = 177806
- 397 + 177409 = 177806
Showing the first eight; more decompositions exist.
