Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185148, here are decompositions:

11 + 185137 = 185148
17 + 185131 = 185148
59 + 185089 = 185148
71 + 185077 = 185148
79 + 185069 = 185148
97 + 185051 = 185148
127 + 185021 = 185148
149 + 184999 = 185148

Showing the first eight; more decompositions exist.
