Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20230, here are decompositions:
- 11 + 20219 = 20230
- 29 + 20201 = 20230
- 47 + 20183 = 20230
- 53 + 20177 = 20230
- 83 + 20147 = 20230
- 101 + 20129 = 20230
- 107 + 20123 = 20230
- 113 + 20117 = 20230
Showing the first eight; more decompositions exist.
