Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30198, here are decompositions:

11 + 30187 = 30198
17 + 30181 = 30198
29 + 30169 = 30198
37 + 30161 = 30198
59 + 30139 = 30198
61 + 30137 = 30198
79 + 30119 = 30198
89 + 30109 = 30198

Showing the first eight; more decompositions exist.
