Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20304, here are decompositions:
- 7 + 20297 = 20304
- 17 + 20287 = 20304
- 43 + 20261 = 20304
- 71 + 20233 = 20304
- 73 + 20231 = 20304
- 103 + 20201 = 20304
- 127 + 20177 = 20304
- 131 + 20173 = 20304
Showing the first eight; more decompositions exist.
