Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89820, here are decompositions:
- 11 + 89809 = 89820
- 23 + 89797 = 89820
- 37 + 89783 = 89820
- 41 + 89779 = 89820
- 53 + 89767 = 89820
- 61 + 89759 = 89820
- 67 + 89753 = 89820
- 131 + 89689 = 89820
Showing the first eight; more decompositions exist.
