Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43680, here are decompositions:
- 11 + 43669 = 43680
- 19 + 43661 = 43680
- 29 + 43651 = 43680
- 31 + 43649 = 43680
- 47 + 43633 = 43680
- 53 + 43627 = 43680
- 67 + 43613 = 43680
- 71 + 43609 = 43680
Showing the first eight; more decompositions exist.
