Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20196, here are decompositions:
- 13 + 20183 = 20196
- 19 + 20177 = 20196
- 23 + 20173 = 20196
- 47 + 20149 = 20196
- 53 + 20143 = 20196
- 67 + 20129 = 20196
- 73 + 20123 = 20196
- 79 + 20117 = 20196
Showing the first eight; more decompositions exist.
