Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20094, here are decompositions:
- 5 + 20089 = 20094
- 23 + 20071 = 20094
- 31 + 20063 = 20094
- 43 + 20051 = 20094
- 47 + 20047 = 20094
- 71 + 20023 = 20094
- 73 + 20021 = 20094
- 83 + 20011 = 20094
Showing the first eight; more decompositions exist.
