Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678216, here are decompositions:
- 3 + 8678213 = 8678216
- 13 + 8678203 = 8678216
- 37 + 8678179 = 8678216
- 67 + 8678149 = 8678216
- 103 + 8678113 = 8678216
- 163 + 8678053 = 8678216
- 223 + 8677993 = 8678216
- 457 + 8677759 = 8678216
Showing the first eight; more decompositions exist.
