Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20302, here are decompositions:
- 5 + 20297 = 20302
- 41 + 20261 = 20302
- 53 + 20249 = 20302
- 71 + 20231 = 20302
- 83 + 20219 = 20302
- 101 + 20201 = 20302
- 173 + 20129 = 20302
- 179 + 20123 = 20302
Showing the first eight; more decompositions exist.
