Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600388, here are decompositions:

29 + 8600359 = 8600388
47 + 8600341 = 8600388
79 + 8600309 = 8600388
149 + 8600239 = 8600388
157 + 8600231 = 8600388
227 + 8600161 = 8600388
317 + 8600071 = 8600388
347 + 8600041 = 8600388

Showing the first eight; more decompositions exist.
