Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20124, here are decompositions:
- 7 + 20117 = 20124
- 11 + 20113 = 20124
- 17 + 20107 = 20124
- 23 + 20101 = 20124
- 53 + 20071 = 20124
- 61 + 20063 = 20124
- 73 + 20051 = 20124
- 101 + 20023 = 20124
Showing the first eight; more decompositions exist.
