Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20272, here are decompositions:
- 3 + 20269 = 20272
- 11 + 20261 = 20272
- 23 + 20249 = 20272
- 41 + 20231 = 20272
- 53 + 20219 = 20272
- 71 + 20201 = 20272
- 89 + 20183 = 20272
- 149 + 20123 = 20272
Showing the first eight; more decompositions exist.
