Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12118, here are decompositions:

5 + 12113 = 12118
11 + 12107 = 12118
17 + 12101 = 12118
47 + 12071 = 12118
107 + 12011 = 12118
131 + 11987 = 12118
137 + 11981 = 12118
149 + 11969 = 12118

Showing the first eight; more decompositions exist.
