Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86404, here are decompositions:
- 5 + 86399 = 86404
- 23 + 86381 = 86404
- 47 + 86357 = 86404
- 53 + 86351 = 86404
- 107 + 86297 = 86404
- 113 + 86291 = 86404
- 233 + 86171 = 86404
- 293 + 86111 = 86404
Showing the first eight; more decompositions exist.
