Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645904, here are decompositions:

5 + 8645899 = 8645904
17 + 8645887 = 8645904
41 + 8645863 = 8645904
101 + 8645803 = 8645904
131 + 8645773 = 8645904
251 + 8645653 = 8645904
257 + 8645647 = 8645904
271 + 8645633 = 8645904

Showing the first eight; more decompositions exist.
