Goldbach decomposition

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.
