Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20700, here are decompositions:
- 7 + 20693 = 20700
- 19 + 20681 = 20700
- 37 + 20663 = 20700
- 59 + 20641 = 20700
- 61 + 20639 = 20700
- 73 + 20627 = 20700
- 89 + 20611 = 20700
- 101 + 20599 = 20700
Showing the first eight; more decompositions exist.
