Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20146, here are decompositions:
- 3 + 20143 = 20146
- 17 + 20129 = 20146
- 23 + 20123 = 20146
- 29 + 20117 = 20146
- 83 + 20063 = 20146
- 149 + 19997 = 20146
- 167 + 19979 = 20146
- 173 + 19973 = 20146
Showing the first eight; more decompositions exist.
