Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13020, here are decompositions:
- 11 + 13009 = 13020
- 13 + 13007 = 13020
- 17 + 13003 = 13020
- 19 + 13001 = 13020
- 37 + 12983 = 13020
- 41 + 12979 = 13020
- 47 + 12973 = 13020
- 53 + 12967 = 13020
Showing the first eight; more decompositions exist.
