Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621484, here are decompositions:

5 + 8621479 = 8621484
7 + 8621477 = 8621484
17 + 8621467 = 8621484
31 + 8621453 = 8621484
41 + 8621443 = 8621484
71 + 8621413 = 8621484
73 + 8621411 = 8621484
107 + 8621377 = 8621484

Showing the first eight; more decompositions exist.
