Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705222, here are decompositions:

3 + 8705219 = 8705222
73 + 8705149 = 8705222
181 + 8705041 = 8705222
193 + 8705029 = 8705222
241 + 8704981 = 8705222
271 + 8704951 = 8705222
313 + 8704909 = 8705222
439 + 8704783 = 8705222

Showing the first eight; more decompositions exist.
