Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20104, here are decompositions:
- 3 + 20101 = 20104
- 41 + 20063 = 20104
- 53 + 20051 = 20104
- 83 + 20021 = 20104
- 107 + 19997 = 20104
- 113 + 19991 = 20104
- 131 + 19973 = 20104
- 167 + 19937 = 20104
Showing the first eight; more decompositions exist.
