Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625388, here are decompositions:

29 + 8625359 = 8625388
71 + 8625317 = 8625388
197 + 8625191 = 8625388
257 + 8625131 = 8625388
269 + 8625119 = 8625388
311 + 8625077 = 8625388
389 + 8624999 = 8625388
467 + 8624921 = 8625388

Showing the first eight; more decompositions exist.
