Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43920, here are decompositions:
- 7 + 43913 = 43920
- 29 + 43891 = 43920
- 31 + 43889 = 43920
- 53 + 43867 = 43920
- 67 + 43853 = 43920
- 127 + 43793 = 43920
- 131 + 43789 = 43920
- 137 + 43783 = 43920
Showing the first eight; more decompositions exist.
