Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678432, here are decompositions:
- 73 + 8678359 = 8678432
- 79 + 8678353 = 8678432
- 109 + 8678323 = 8678432
- 229 + 8678203 = 8678432
- 271 + 8678161 = 8678432
- 283 + 8678149 = 8678432
- 349 + 8678083 = 8678432
- 379 + 8678053 = 8678432
Showing the first eight; more decompositions exist.
