Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30186, here are decompositions:

5 + 30181 = 30186
17 + 30169 = 30186
47 + 30139 = 30186
53 + 30133 = 30186
67 + 30119 = 30186
73 + 30113 = 30186
83 + 30103 = 30186
89 + 30097 = 30186

Showing the first eight; more decompositions exist.
