Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82564, here are decompositions:
- 3 + 82561 = 82564
- 5 + 82559 = 82564
- 71 + 82493 = 82564
- 101 + 82463 = 82564
- 107 + 82457 = 82564
- 191 + 82373 = 82564
- 257 + 82307 = 82564
- 263 + 82301 = 82564
Showing the first eight; more decompositions exist.
