Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662, here are decompositions:
- 53 + 8609 = 8662
- 89 + 8573 = 8662
- 149 + 8513 = 8662
- 233 + 8429 = 8662
- 239 + 8423 = 8662
- 293 + 8369 = 8662
- 389 + 8273 = 8662
- 419 + 8243 = 8662
Showing the first eight; more decompositions exist.
