Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30012, here are decompositions:

23 + 29989 = 30012
29 + 29983 = 30012
53 + 29959 = 30012
131 + 29881 = 30012
139 + 29873 = 30012
149 + 29863 = 30012
179 + 29833 = 30012
193 + 29819 = 30012

Showing the first eight; more decompositions exist.
