Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684628, here are decompositions:

31 + 8684597 = 8684628
41 + 8684587 = 8684628
107 + 8684521 = 8684628
149 + 8684479 = 8684628
157 + 8684471 = 8684628
167 + 8684461 = 8684628
191 + 8684437 = 8684628
269 + 8684359 = 8684628

Showing the first eight; more decompositions exist.
