Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12162, here are decompositions:

5 + 12157 = 12162
13 + 12149 = 12162
19 + 12143 = 12162
43 + 12119 = 12162
53 + 12109 = 12162
61 + 12101 = 12162
89 + 12073 = 12162
113 + 12049 = 12162

Showing the first eight; more decompositions exist.
