Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30118, here are decompositions:

5 + 30113 = 30118
29 + 30089 = 30118
47 + 30071 = 30118
59 + 30059 = 30118
71 + 30047 = 30118
89 + 30029 = 30118
107 + 30011 = 30118
191 + 29927 = 30118

Showing the first eight; more decompositions exist.
