Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12160, here are decompositions:

3 + 12157 = 12160
11 + 12149 = 12160
17 + 12143 = 12160
41 + 12119 = 12160
47 + 12113 = 12160
53 + 12107 = 12160
59 + 12101 = 12160
89 + 12071 = 12160

Showing the first eight; more decompositions exist.
