Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625904, here are decompositions:

3 + 8625901 = 8625904
71 + 8625833 = 8625904
83 + 8625821 = 8625904
197 + 8625707 = 8625904
263 + 8625641 = 8625904
317 + 8625587 = 8625904
383 + 8625521 = 8625904
587 + 8625317 = 8625904

Showing the first eight; more decompositions exist.
