Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16120, here are decompositions:

17 + 16103 = 16120
23 + 16097 = 16120
29 + 16091 = 16120
47 + 16073 = 16120
53 + 16067 = 16120
59 + 16061 = 16120
113 + 16007 = 16120
149 + 15971 = 16120

Showing the first eight; more decompositions exist.
