Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85678, here are decompositions:
- 11 + 85667 = 85678
- 17 + 85661 = 85678
- 59 + 85619 = 85678
- 71 + 85607 = 85678
- 101 + 85577 = 85678
- 107 + 85571 = 85678
- 191 + 85487 = 85678
- 227 + 85451 = 85678
Showing the first eight; more decompositions exist.
