Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82820, here are decompositions:
- 7 + 82813 = 82820
- 61 + 82759 = 82820
- 97 + 82723 = 82820
- 163 + 82657 = 82820
- 211 + 82609 = 82820
- 229 + 82591 = 82820
- 271 + 82549 = 82820
- 313 + 82507 = 82820
Showing the first eight; more decompositions exist.
