Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5218, here are decompositions:
- 29 + 5189 = 5218
- 47 + 5171 = 5218
- 71 + 5147 = 5218
- 131 + 5087 = 5218
- 137 + 5081 = 5218
- 167 + 5051 = 5218
- 179 + 5039 = 5218
- 197 + 5021 = 5218
Showing the first eight; more decompositions exist.
