Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82566, here are decompositions:
- 5 + 82561 = 82566
- 7 + 82559 = 82566
- 17 + 82549 = 82566
- 37 + 82529 = 82566
- 59 + 82507 = 82566
- 67 + 82499 = 82566
- 73 + 82493 = 82566
- 79 + 82487 = 82566
Showing the first eight; more decompositions exist.
