Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82512, here are decompositions:
- 5 + 82507 = 82512
- 13 + 82499 = 82512
- 19 + 82493 = 82512
- 29 + 82483 = 82512
- 41 + 82471 = 82512
- 43 + 82469 = 82512
- 139 + 82373 = 82512
- 151 + 82361 = 82512
Showing the first eight; more decompositions exist.
