Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28910, here are decompositions:
- 31 + 28879 = 28910
- 43 + 28867 = 28910
- 67 + 28843 = 28910
- 73 + 28837 = 28910
- 97 + 28813 = 28910
- 103 + 28807 = 28910
- 139 + 28771 = 28910
- 151 + 28759 = 28910
Showing the first eight; more decompositions exist.
