Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704428, here are decompositions:

11 + 8704417 = 8704428
59 + 8704369 = 8704428
97 + 8704331 = 8704428
149 + 8704279 = 8704428
199 + 8704229 = 8704428
269 + 8704159 = 8704428
307 + 8704121 = 8704428
311 + 8704117 = 8704428

Showing the first eight; more decompositions exist.
