Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28826, here are decompositions:
- 13 + 28813 = 28826
- 19 + 28807 = 28826
- 37 + 28789 = 28826
- 67 + 28759 = 28826
- 73 + 28753 = 28826
- 97 + 28729 = 28826
- 103 + 28723 = 28826
- 139 + 28687 = 28826
Showing the first eight; more decompositions exist.
