Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28884, here are decompositions:
- 5 + 28879 = 28884
- 13 + 28871 = 28884
- 17 + 28867 = 28884
- 41 + 28843 = 28884
- 47 + 28837 = 28884
- 67 + 28817 = 28884
- 71 + 28813 = 28884
- 113 + 28771 = 28884
Showing the first eight; more decompositions exist.
