Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89880, here are decompositions:
- 13 + 89867 = 89880
- 31 + 89849 = 89880
- 41 + 89839 = 89880
- 47 + 89833 = 89880
- 59 + 89821 = 89880
- 61 + 89819 = 89880
- 71 + 89809 = 89880
- 83 + 89797 = 89880
Showing the first eight; more decompositions exist.
