Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76820, here are decompositions:
- 19 + 76801 = 76820
- 43 + 76777 = 76820
- 67 + 76753 = 76820
- 103 + 76717 = 76820
- 223 + 76597 = 76820
- 241 + 76579 = 76820
- 277 + 76543 = 76820
- 283 + 76537 = 76820
Showing the first eight; more decompositions exist.
