Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678424, here are decompositions:
- 31 + 8678393 = 8678424
- 61 + 8678363 = 8678424
- 71 + 8678353 = 8678424
- 101 + 8678323 = 8678424
- 113 + 8678311 = 8678424
- 211 + 8678213 = 8678424
- 263 + 8678161 = 8678424
- 277 + 8678147 = 8678424
Showing the first eight; more decompositions exist.
