Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718288, here are decompositions:
- 11 + 8718277 = 8718288
- 17 + 8718271 = 8718288
- 37 + 8718251 = 8718288
- 41 + 8718247 = 8718288
- 67 + 8718221 = 8718288
- 71 + 8718217 = 8718288
- 97 + 8718191 = 8718288
- 179 + 8718109 = 8718288
Showing the first eight; more decompositions exist.
