Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32880, here are decompositions:
- 11 + 32869 = 32880
- 37 + 32843 = 32880
- 41 + 32839 = 32880
- 47 + 32833 = 32880
- 79 + 32801 = 32880
- 83 + 32797 = 32880
- 97 + 32783 = 32880
- 101 + 32779 = 32880
Showing the first eight; more decompositions exist.
