Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86564, here are decompositions:
- 3 + 86561 = 86564
- 31 + 86533 = 86564
- 73 + 86491 = 86564
- 97 + 86467 = 86564
- 103 + 86461 = 86564
- 151 + 86413 = 86564
- 193 + 86371 = 86564
- 211 + 86353 = 86564
Showing the first eight; more decompositions exist.
