Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182142, here are decompositions:

11 + 182131 = 182142
13 + 182129 = 182142
19 + 182123 = 182142
31 + 182111 = 182142
41 + 182101 = 182142
43 + 182099 = 182142
53 + 182089 = 182142
83 + 182059 = 182142

Showing the first eight; more decompositions exist.
