Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678208, here are decompositions:
- 5 + 8678203 = 8678208
- 29 + 8678179 = 8678208
- 47 + 8678161 = 8678208
- 59 + 8678149 = 8678208
- 61 + 8678147 = 8678208
- 67 + 8678141 = 8678208
- 79 + 8678129 = 8678208
- 127 + 8678081 = 8678208
Showing the first eight; more decompositions exist.
