Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85690, here are decompositions:
- 23 + 85667 = 85690
- 29 + 85661 = 85690
- 47 + 85643 = 85690
- 71 + 85619 = 85690
- 83 + 85607 = 85690
- 89 + 85601 = 85690
- 113 + 85577 = 85690
- 167 + 85523 = 85690
Showing the first eight; more decompositions exist.
