Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8218, here are decompositions:
- 47 + 8171 = 8218
- 71 + 8147 = 8218
- 101 + 8117 = 8218
- 107 + 8111 = 8218
- 131 + 8087 = 8218
- 137 + 8081 = 8218
- 149 + 8069 = 8218
- 179 + 8039 = 8218
Showing the first eight; more decompositions exist.
