Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628574, here are decompositions:

23 + 8628551 = 8628574
131 + 8628443 = 8628574
167 + 8628407 = 8628574
191 + 8628383 = 8628574
197 + 8628377 = 8628574
281 + 8628293 = 8628574
401 + 8628173 = 8628574
443 + 8628131 = 8628574

Showing the first eight; more decompositions exist.
