Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621532, here are decompositions:

41 + 8621491 = 8621532
53 + 8621479 = 8621532
79 + 8621453 = 8621532
89 + 8621443 = 8621532
103 + 8621429 = 8621532
193 + 8621339 = 8621532
223 + 8621309 = 8621532
233 + 8621299 = 8621532

Showing the first eight; more decompositions exist.
