Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10920, here are decompositions:
- 11 + 10909 = 10920
- 17 + 10903 = 10920
- 29 + 10891 = 10920
- 31 + 10889 = 10920
- 37 + 10883 = 10920
- 53 + 10867 = 10920
- 59 + 10861 = 10920
- 61 + 10859 = 10920
Showing the first eight; more decompositions exist.
