Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30854, here are decompositions:

3 + 30851 = 30854
13 + 30841 = 30854
37 + 30817 = 30854
73 + 30781 = 30854
97 + 30757 = 30854
127 + 30727 = 30854
151 + 30703 = 30854
157 + 30697 = 30854

Showing the first eight; more decompositions exist.
