Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625724, here are decompositions:

17 + 8625707 = 8625724
83 + 8625641 = 8625724
137 + 8625587 = 8625724
197 + 8625527 = 8625724
257 + 8625467 = 8625724
293 + 8625431 = 8625724
461 + 8625263 = 8625724
491 + 8625233 = 8625724

Showing the first eight; more decompositions exist.
