Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20616, here are decompositions:
- 5 + 20611 = 20616
- 17 + 20599 = 20616
- 23 + 20593 = 20616
- 53 + 20563 = 20616
- 67 + 20549 = 20616
- 73 + 20543 = 20616
- 83 + 20533 = 20616
- 107 + 20509 = 20616
Showing the first eight; more decompositions exist.
