Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185164, here are decompositions:

3 + 185161 = 185164
11 + 185153 = 185164
41 + 185123 = 185164
101 + 185063 = 185164
107 + 185057 = 185164
113 + 185051 = 185164
137 + 185027 = 185164
167 + 184997 = 185164

Showing the first eight; more decompositions exist.
