Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82880, here are decompositions:
- 43 + 82837 = 82880
- 67 + 82813 = 82880
- 151 + 82729 = 82880
- 157 + 82723 = 82880
- 181 + 82699 = 82880
- 223 + 82657 = 82880
- 229 + 82651 = 82880
- 271 + 82609 = 82880
Showing the first eight; more decompositions exist.
