Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705200, here are decompositions:

17 + 8705183 = 8705200
29 + 8705171 = 8705200
41 + 8705159 = 8705200
89 + 8705111 = 8705200
107 + 8705093 = 8705200
113 + 8705087 = 8705200
131 + 8705069 = 8705200
149 + 8705051 = 8705200

Showing the first eight; more decompositions exist.
