Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12178, here are decompositions:

17 + 12161 = 12178
29 + 12149 = 12178
59 + 12119 = 12178
71 + 12107 = 12178
107 + 12071 = 12178
137 + 12041 = 12178
167 + 12011 = 12178
191 + 11987 = 12178

Showing the first eight; more decompositions exist.
