Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177782, here are decompositions:
- 19 + 177763 = 177782
- 43 + 177739 = 177782
- 103 + 177679 = 177782
- 181 + 177601 = 177782
- 193 + 177589 = 177782
- 229 + 177553 = 177782
- 271 + 177511 = 177782
- 349 + 177433 = 177782
Showing the first eight; more decompositions exist.
