Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86684, here are decompositions:
- 7 + 86677 = 86684
- 97 + 86587 = 86684
- 151 + 86533 = 86684
- 193 + 86491 = 86684
- 223 + 86461 = 86684
- 271 + 86413 = 86684
- 313 + 86371 = 86684
- 331 + 86353 = 86684
Showing the first eight; more decompositions exist.
