Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8506, here are decompositions:
- 5 + 8501 = 8506
- 59 + 8447 = 8506
- 83 + 8423 = 8506
- 137 + 8369 = 8506
- 233 + 8273 = 8506
- 263 + 8243 = 8506
- 269 + 8237 = 8506
- 359 + 8147 = 8506
Showing the first eight; more decompositions exist.
