Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182178, here are decompositions:

11 + 182167 = 182178
19 + 182159 = 182178
37 + 182141 = 182178
47 + 182131 = 182178
67 + 182111 = 182178
71 + 182107 = 182178
79 + 182099 = 182178
89 + 182089 = 182178

Showing the first eight; more decompositions exist.
