Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705260, here are decompositions:

23 + 8705237 = 8705260
41 + 8705219 = 8705260
89 + 8705171 = 8705260
101 + 8705159 = 8705260
149 + 8705111 = 8705260
167 + 8705093 = 8705260
173 + 8705087 = 8705260
191 + 8705069 = 8705260

Showing the first eight; more decompositions exist.
