Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12072, here are decompositions:

23 + 12049 = 12072
29 + 12043 = 12072
31 + 12041 = 12072
61 + 12011 = 12072
101 + 11971 = 12072
103 + 11969 = 12072
113 + 11959 = 12072
131 + 11941 = 12072

Showing the first eight; more decompositions exist.
