Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13086, here are decompositions:
- 23 + 13063 = 13086
- 37 + 13049 = 13086
- 43 + 13043 = 13086
- 53 + 13033 = 13086
- 79 + 13007 = 13086
- 83 + 13003 = 13086
- 103 + 12983 = 13086
- 107 + 12979 = 13086
Showing the first eight; more decompositions exist.
