Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177760, here are decompositions:
- 17 + 177743 = 177760
- 83 + 177677 = 177760
- 113 + 177647 = 177760
- 137 + 177623 = 177760
- 227 + 177533 = 177760
- 293 + 177467 = 177760
- 491 + 177269 = 177760
- 503 + 177257 = 177760
Showing the first eight; more decompositions exist.
