Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28250, here are decompositions:
- 31 + 28219 = 28250
- 67 + 28183 = 28250
- 127 + 28123 = 28250
- 139 + 28111 = 28250
- 151 + 28099 = 28250
- 163 + 28087 = 28250
- 181 + 28069 = 28250
- 193 + 28057 = 28250
Showing the first eight; more decompositions exist.
