Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28896, here are decompositions:
- 17 + 28879 = 28896
- 29 + 28867 = 28896
- 37 + 28859 = 28896
- 53 + 28843 = 28896
- 59 + 28837 = 28896
- 79 + 28817 = 28896
- 83 + 28813 = 28896
- 89 + 28807 = 28896
Showing the first eight; more decompositions exist.
