Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20650, here are decompositions:
- 11 + 20639 = 20650
- 23 + 20627 = 20650
- 101 + 20549 = 20650
- 107 + 20543 = 20650
- 167 + 20483 = 20650
- 173 + 20477 = 20650
- 239 + 20411 = 20650
- 251 + 20399 = 20650
Showing the first eight; more decompositions exist.
