Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184142, here are decompositions:

31 + 184111 = 184142
61 + 184081 = 184142
103 + 184039 = 184142
139 + 184003 = 184142
163 + 183979 = 184142
193 + 183949 = 184142
199 + 183943 = 184142
223 + 183919 = 184142

Showing the first eight; more decompositions exist.
