Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12108, here are decompositions:

7 + 12101 = 12108
11 + 12097 = 12108
37 + 12071 = 12108
59 + 12049 = 12108
67 + 12041 = 12108
71 + 12037 = 12108
97 + 12011 = 12108
101 + 12007 = 12108

Showing the first eight; more decompositions exist.
