Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86424, here are decompositions:
- 11 + 86413 = 86424
- 43 + 86381 = 86424
- 53 + 86371 = 86424
- 67 + 86357 = 86424
- 71 + 86353 = 86424
- 73 + 86351 = 86424
- 83 + 86341 = 86424
- 101 + 86323 = 86424
Showing the first eight; more decompositions exist.
