Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30884, here are decompositions:
- 3 + 30881 = 30884
- 13 + 30871 = 30884
- 31 + 30853 = 30884
- 43 + 30841 = 30884
- 67 + 30817 = 30884
- 103 + 30781 = 30884
- 127 + 30757 = 30884
- 157 + 30727 = 30884
Showing the first eight; more decompositions exist.
