Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30184, here are decompositions:

3 + 30181 = 30184
23 + 30161 = 30184
47 + 30137 = 30184
71 + 30113 = 30184
113 + 30071 = 30184
137 + 30047 = 30184
173 + 30011 = 30184
257 + 29927 = 30184

Showing the first eight; more decompositions exist.
