Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30924, here are decompositions:
- 13 + 30911 = 30924
- 31 + 30893 = 30924
- 43 + 30881 = 30924
- 53 + 30871 = 30924
- 71 + 30853 = 30924
- 73 + 30851 = 30924
- 83 + 30841 = 30924
- 107 + 30817 = 30924
Showing the first eight; more decompositions exist.
