Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28164, here are decompositions:
- 13 + 28151 = 28164
- 41 + 28123 = 28164
- 53 + 28111 = 28164
- 67 + 28097 = 28164
- 83 + 28081 = 28164
- 107 + 28057 = 28164
- 113 + 28051 = 28164
- 137 + 28027 = 28164
Showing the first eight; more decompositions exist.
