Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20184, here are decompositions:
- 7 + 20177 = 20184
- 11 + 20173 = 20184
- 23 + 20161 = 20184
- 37 + 20147 = 20184
- 41 + 20143 = 20184
- 61 + 20123 = 20184
- 67 + 20117 = 20184
- 71 + 20113 = 20184
Showing the first eight; more decompositions exist.
