Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177620, here are decompositions:
- 19 + 177601 = 177620
- 31 + 177589 = 177620
- 67 + 177553 = 177620
- 109 + 177511 = 177620
- 127 + 177493 = 177620
- 139 + 177481 = 177620
- 193 + 177427 = 177620
- 199 + 177421 = 177620
Showing the first eight; more decompositions exist.
