Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705232, here are decompositions:

13 + 8705219 = 8705232
61 + 8705171 = 8705232
73 + 8705159 = 8705232
83 + 8705149 = 8705232
139 + 8705093 = 8705232
163 + 8705069 = 8705232
181 + 8705051 = 8705232
191 + 8705041 = 8705232

Showing the first eight; more decompositions exist.
