Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185212, here are decompositions:

23 + 185189 = 185212
29 + 185183 = 185212
59 + 185153 = 185212
89 + 185123 = 185212
113 + 185099 = 185212
149 + 185063 = 185212
191 + 185021 = 185212
263 + 184949 = 185212

Showing the first eight; more decompositions exist.
