Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30950, here are decompositions:
- 13 + 30937 = 30950
- 19 + 30931 = 30950
- 79 + 30871 = 30950
- 97 + 30853 = 30950
- 109 + 30841 = 30950
- 193 + 30757 = 30950
- 223 + 30727 = 30950
- 307 + 30643 = 30950
Showing the first eight; more decompositions exist.
