Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30888, here are decompositions:
- 7 + 30881 = 30888
- 17 + 30871 = 30888
- 19 + 30869 = 30888
- 29 + 30859 = 30888
- 37 + 30851 = 30888
- 47 + 30841 = 30888
- 59 + 30829 = 30888
- 71 + 30817 = 30888
Showing the first eight; more decompositions exist.
