Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164178, here are decompositions:

5 + 164173 = 164178
29 + 164149 = 164178
31 + 164147 = 164178
61 + 164117 = 164178
89 + 164089 = 164178
107 + 164071 = 164178
127 + 164051 = 164178
139 + 164039 = 164178

Showing the first eight; more decompositions exist.
