Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621396, here are decompositions:

19 + 8621377 = 8621396
97 + 8621299 = 8621396
307 + 8621089 = 8621396
313 + 8621083 = 8621396
349 + 8621047 = 8621396
379 + 8621017 = 8621396
499 + 8620897 = 8621396
523 + 8620873 = 8621396

Showing the first eight; more decompositions exist.
