Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28106, here are decompositions:
- 7 + 28099 = 28106
- 19 + 28087 = 28106
- 37 + 28069 = 28106
- 79 + 28027 = 28106
- 109 + 27997 = 28106
- 139 + 27967 = 28106
- 163 + 27943 = 28106
- 223 + 27883 = 28106
Showing the first eight; more decompositions exist.
