Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28148, here are decompositions:
- 37 + 28111 = 28148
- 61 + 28087 = 28148
- 67 + 28081 = 28148
- 79 + 28069 = 28148
- 97 + 28051 = 28148
- 151 + 27997 = 28148
- 181 + 27967 = 28148
- 229 + 27919 = 28148
Showing the first eight; more decompositions exist.
