Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164148, here are decompositions:

31 + 164117 = 164148
59 + 164089 = 164148
97 + 164051 = 164148
109 + 164039 = 164148
137 + 164011 = 164148
151 + 163997 = 164148
157 + 163991 = 164148
167 + 163981 = 164148

Showing the first eight; more decompositions exist.
