Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30166, here are decompositions:

5 + 30161 = 30166
29 + 30137 = 30166
47 + 30119 = 30166
53 + 30113 = 30166
107 + 30059 = 30166
137 + 30029 = 30166
239 + 29927 = 30166
293 + 29873 = 30166

Showing the first eight; more decompositions exist.
