Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85224, here are decompositions:
- 11 + 85213 = 85224
- 23 + 85201 = 85224
- 31 + 85193 = 85224
- 103 + 85121 = 85224
- 131 + 85093 = 85224
- 137 + 85087 = 85224
- 163 + 85061 = 85224
- 197 + 85027 = 85224
Showing the first eight; more decompositions exist.
