Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30896, here are decompositions:

3 + 30893 = 30896
37 + 30859 = 30896
43 + 30853 = 30896
67 + 30829 = 30896
79 + 30817 = 30896
139 + 30757 = 30896
193 + 30703 = 30896
199 + 30697 = 30896

Showing the first eight; more decompositions exist.
