Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20220, here are decompositions:
- 19 + 20201 = 20220
- 37 + 20183 = 20220
- 43 + 20177 = 20220
- 47 + 20173 = 20220
- 59 + 20161 = 20220
- 71 + 20149 = 20220
- 73 + 20147 = 20220
- 97 + 20123 = 20220
Showing the first eight; more decompositions exist.
