Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30136, here are decompositions:

3 + 30133 = 30136
17 + 30119 = 30136
23 + 30113 = 30136
47 + 30089 = 30136
89 + 30047 = 30136
107 + 30029 = 30136
257 + 29879 = 30136
263 + 29873 = 30136

Showing the first eight; more decompositions exist.
