Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678478, here are decompositions:
- 5 + 8678473 = 8678478
- 31 + 8678447 = 8678478
- 79 + 8678399 = 8678478
- 139 + 8678339 = 8678478
- 167 + 8678311 = 8678478
- 241 + 8678237 = 8678478
- 317 + 8678161 = 8678478
- 331 + 8678147 = 8678478
Showing the first eight; more decompositions exist.
