Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12142, here are decompositions:

23 + 12119 = 12142
29 + 12113 = 12142
41 + 12101 = 12142
71 + 12071 = 12142
101 + 12041 = 12142
131 + 12011 = 12142
173 + 11969 = 12142
233 + 11909 = 12142

Showing the first eight; more decompositions exist.
