Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30948, here are decompositions:
- 7 + 30941 = 30948
- 11 + 30937 = 30948
- 17 + 30931 = 30948
- 37 + 30911 = 30948
- 67 + 30881 = 30948
- 79 + 30869 = 30948
- 89 + 30859 = 30948
- 97 + 30851 = 30948
Showing the first eight; more decompositions exist.
