Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12030, here are decompositions:

19 + 12011 = 12030
23 + 12007 = 12030
43 + 11987 = 12030
59 + 11971 = 12030
61 + 11969 = 12030
71 + 11959 = 12030
89 + 11941 = 12030
97 + 11933 = 12030

Showing the first eight; more decompositions exist.
