Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20250, here are decompositions:
- 17 + 20233 = 20250
- 19 + 20231 = 20250
- 31 + 20219 = 20250
- 67 + 20183 = 20250
- 73 + 20177 = 20250
- 89 + 20161 = 20250
- 101 + 20149 = 20250
- 103 + 20147 = 20250
Showing the first eight; more decompositions exist.
