Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177866, here are decompositions:
- 43 + 177823 = 177866
- 79 + 177787 = 177866
- 103 + 177763 = 177866
- 127 + 177739 = 177866
- 277 + 177589 = 177866
- 313 + 177553 = 177866
- 373 + 177493 = 177866
- 379 + 177487 = 177866
Showing the first eight; more decompositions exist.
