Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30188, here are decompositions:

7 + 30181 = 30188
19 + 30169 = 30188
79 + 30109 = 30188
97 + 30091 = 30188
199 + 29989 = 30188
229 + 29959 = 30188
241 + 29947 = 30188
271 + 29917 = 30188

Showing the first eight; more decompositions exist.
