Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689408, here are decompositions:

59 + 8689349 = 8689408
89 + 8689319 = 8689408
107 + 8689301 = 8689408
149 + 8689259 = 8689408
191 + 8689217 = 8689408
227 + 8689181 = 8689408
239 + 8689169 = 8689408
311 + 8689097 = 8689408

Showing the first eight; more decompositions exist.
