Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186142, here are decompositions:

23 + 186119 = 186142
29 + 186113 = 186142
71 + 186071 = 186142
101 + 186041 = 186142
149 + 185993 = 186142
191 + 185951 = 186142
239 + 185903 = 186142
269 + 185873 = 186142

Showing the first eight; more decompositions exist.
