Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12154, here are decompositions:

5 + 12149 = 12154
11 + 12143 = 12154
41 + 12113 = 12154
47 + 12107 = 12154
53 + 12101 = 12154
83 + 12071 = 12154
113 + 12041 = 12154
167 + 11987 = 12154

Showing the first eight; more decompositions exist.
