Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82500, here are decompositions:
- 7 + 82493 = 82500
- 13 + 82487 = 82500
- 17 + 82483 = 82500
- 29 + 82471 = 82500
- 31 + 82469 = 82500
- 37 + 82463 = 82500
- 43 + 82457 = 82500
- 79 + 82421 = 82500
Showing the first eight; more decompositions exist.
