Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30904, here are decompositions:
- 11 + 30893 = 30904
- 23 + 30881 = 30904
- 53 + 30851 = 30904
- 101 + 30803 = 30904
- 131 + 30773 = 30904
- 191 + 30713 = 30904
- 197 + 30707 = 30904
- 227 + 30677 = 30904
Showing the first eight; more decompositions exist.
