Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688424, here are decompositions:
- 71 + 8688353 = 8688424
- 113 + 8688311 = 8688424
- 137 + 8688287 = 8688424
- 257 + 8688167 = 8688424
- 263 + 8688161 = 8688424
- 281 + 8688143 = 8688424
- 347 + 8688077 = 8688424
- 431 + 8687993 = 8688424
Showing the first eight; more decompositions exist.
