Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12130, here are decompositions:

11 + 12119 = 12130
17 + 12113 = 12130
23 + 12107 = 12130
29 + 12101 = 12130
59 + 12071 = 12130
89 + 12041 = 12130
149 + 11981 = 12130
191 + 11939 = 12130

Showing the first eight; more decompositions exist.
