Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621318, here are decompositions:

19 + 8621299 = 8621318
37 + 8621281 = 8621318
109 + 8621209 = 8621318
229 + 8621089 = 8621318
241 + 8621077 = 8621318
271 + 8621047 = 8621318
367 + 8620951 = 8621318
421 + 8620897 = 8621318

Showing the first eight; more decompositions exist.
