Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30912, here are decompositions:
- 19 + 30893 = 30912
- 31 + 30881 = 30912
- 41 + 30871 = 30912
- 43 + 30869 = 30912
- 53 + 30859 = 30912
- 59 + 30853 = 30912
- 61 + 30851 = 30912
- 71 + 30841 = 30912
Showing the first eight; more decompositions exist.
