Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20706, here are decompositions:
- 13 + 20693 = 20706
- 43 + 20663 = 20706
- 67 + 20639 = 20706
- 79 + 20627 = 20706
- 107 + 20599 = 20706
- 113 + 20593 = 20706
- 157 + 20549 = 20706
- 163 + 20543 = 20706
Showing the first eight; more decompositions exist.
