Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89872, here are decompositions:
- 5 + 89867 = 89872
- 23 + 89849 = 89872
- 53 + 89819 = 89872
- 89 + 89783 = 89872
- 113 + 89759 = 89872
- 191 + 89681 = 89872
- 239 + 89633 = 89872
- 269 + 89603 = 89872
Showing the first eight; more decompositions exist.
