Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28916, here are decompositions:
- 7 + 28909 = 28916
- 37 + 28879 = 28916
- 73 + 28843 = 28916
- 79 + 28837 = 28916
- 103 + 28813 = 28916
- 109 + 28807 = 28916
- 127 + 28789 = 28916
- 157 + 28759 = 28916
Showing the first eight; more decompositions exist.
