Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185170, here are decompositions:

3 + 185167 = 185170
17 + 185153 = 185170
47 + 185123 = 185170
71 + 185099 = 185170
101 + 185069 = 185170
107 + 185063 = 185170
113 + 185057 = 185170
149 + 185021 = 185170

Showing the first eight; more decompositions exist.
