Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621472, here are decompositions:

5 + 8621467 = 8621472
19 + 8621453 = 8621472
29 + 8621443 = 8621472
43 + 8621429 = 8621472
59 + 8621413 = 8621472
61 + 8621411 = 8621472
163 + 8621309 = 8621472
173 + 8621299 = 8621472

Showing the first eight; more decompositions exist.
