Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28950, here are decompositions:
- 17 + 28933 = 28950
- 23 + 28927 = 28950
- 29 + 28921 = 28950
- 41 + 28909 = 28950
- 71 + 28879 = 28950
- 79 + 28871 = 28950
- 83 + 28867 = 28950
- 107 + 28843 = 28950
Showing the first eight; more decompositions exist.
