Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28160, here are decompositions:
- 37 + 28123 = 28160
- 61 + 28099 = 28160
- 73 + 28087 = 28160
- 79 + 28081 = 28160
- 103 + 28057 = 28160
- 109 + 28051 = 28160
- 163 + 27997 = 28160
- 193 + 27967 = 28160
Showing the first eight; more decompositions exist.
