Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16072, here are decompositions:

3 + 16069 = 16072
5 + 16067 = 16072
11 + 16061 = 16072
71 + 16001 = 16072
101 + 15971 = 16072
113 + 15959 = 16072
149 + 15923 = 16072
191 + 15881 = 16072

Showing the first eight; more decompositions exist.
