Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706208, here are decompositions:

11 + 8706197 = 8706208
59 + 8706149 = 8706208
101 + 8706107 = 8706208
107 + 8706101 = 8706208
149 + 8706059 = 8706208
197 + 8706011 = 8706208
239 + 8705969 = 8706208
347 + 8705861 = 8706208

Showing the first eight; more decompositions exist.
