Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8136, here are decompositions:
- 13 + 8123 = 8136
- 19 + 8117 = 8136
- 43 + 8093 = 8136
- 47 + 8089 = 8136
- 67 + 8069 = 8136
- 83 + 8053 = 8136
- 97 + 8039 = 8136
- 127 + 8009 = 8136
Showing the first eight; more decompositions exist.
