Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185122, here are decompositions:

23 + 185099 = 185122
53 + 185069 = 185122
59 + 185063 = 185122
71 + 185051 = 185122
101 + 185021 = 185122
173 + 184949 = 185122
263 + 184859 = 185122
293 + 184829 = 185122

Showing the first eight; more decompositions exist.
