Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7868, here are decompositions:
- 79 + 7789 = 7868
- 109 + 7759 = 7868
- 127 + 7741 = 7868
- 151 + 7717 = 7868
- 181 + 7687 = 7868
- 199 + 7669 = 7868
- 229 + 7639 = 7868
- 277 + 7591 = 7868
Showing the first eight; more decompositions exist.
