Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621468, here are decompositions:

367 + 8621101 = 8621468
379 + 8621089 = 8621468
421 + 8621047 = 8621468
571 + 8620897 = 8621468
607 + 8620861 = 8621468
829 + 8620639 = 8621468
1039 + 8620429 = 8621468
1201 + 8620267 = 8621468

Showing the first eight; more decompositions exist.
