Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85684, here are decompositions:
- 17 + 85667 = 85684
- 23 + 85661 = 85684
- 41 + 85643 = 85684
- 83 + 85601 = 85684
- 107 + 85577 = 85684
- 113 + 85571 = 85684
- 167 + 85517 = 85684
- 197 + 85487 = 85684
Showing the first eight; more decompositions exist.
