Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8436, here are decompositions:
- 5 + 8431 = 8436
- 7 + 8429 = 8436
- 13 + 8423 = 8436
- 17 + 8419 = 8436
- 47 + 8389 = 8436
- 59 + 8377 = 8436
- 67 + 8369 = 8436
- 73 + 8363 = 8436
Showing the first eight; more decompositions exist.
