Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28946, here are decompositions:
- 13 + 28933 = 28946
- 19 + 28927 = 28946
- 37 + 28909 = 28946
- 67 + 28879 = 28946
- 79 + 28867 = 28946
- 103 + 28843 = 28946
- 109 + 28837 = 28946
- 139 + 28807 = 28946
Showing the first eight; more decompositions exist.
