Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621610, here are decompositions:

29 + 8621581 = 8621610
59 + 8621551 = 8621610
131 + 8621479 = 8621610
157 + 8621453 = 8621610
167 + 8621443 = 8621610
181 + 8621429 = 8621610
197 + 8621413 = 8621610
199 + 8621411 = 8621610

Showing the first eight; more decompositions exist.
