Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718500, here are decompositions:
- 13 + 8718487 = 8718500
- 31 + 8718469 = 8718500
- 61 + 8718439 = 8718500
- 73 + 8718427 = 8718500
- 151 + 8718349 = 8718500
- 157 + 8718343 = 8718500
- 199 + 8718301 = 8718500
- 223 + 8718277 = 8718500
Showing the first eight; more decompositions exist.
