Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82020, here are decompositions:
- 7 + 82013 = 82020
- 11 + 82009 = 82020
- 13 + 82007 = 82020
- 17 + 82003 = 82020
- 47 + 81973 = 82020
- 53 + 81967 = 82020
- 67 + 81953 = 82020
- 83 + 81937 = 82020
Showing the first eight; more decompositions exist.
