Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28908, here are decompositions:
- 7 + 28901 = 28908
- 29 + 28879 = 28908
- 37 + 28871 = 28908
- 41 + 28867 = 28908
- 71 + 28837 = 28908
- 101 + 28807 = 28908
- 137 + 28771 = 28908
- 149 + 28759 = 28908
Showing the first eight; more decompositions exist.
