Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28152, here are decompositions:
- 29 + 28123 = 28152
- 41 + 28111 = 28152
- 43 + 28109 = 28152
- 53 + 28099 = 28152
- 71 + 28081 = 28152
- 83 + 28069 = 28152
- 101 + 28051 = 28152
- 151 + 28001 = 28152
Showing the first eight; more decompositions exist.
