Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170828, here are decompositions:
- 19 + 170809 = 170828
- 61 + 170767 = 170828
- 67 + 170761 = 170828
- 79 + 170749 = 170828
- 127 + 170701 = 170828
- 139 + 170689 = 170828
- 181 + 170647 = 170828
- 271 + 170557 = 170828
Showing the first eight; more decompositions exist.
