Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30194, here are decompositions:

7 + 30187 = 30194
13 + 30181 = 30194
61 + 30133 = 30194
97 + 30097 = 30194
103 + 30091 = 30194
181 + 30013 = 30194
211 + 29983 = 30194
277 + 29917 = 30194

Showing the first eight; more decompositions exist.
