Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620610, here are decompositions:

7 + 8620603 = 8620610
43 + 8620567 = 8620610
67 + 8620543 = 8620610
181 + 8620429 = 8620610
241 + 8620369 = 8620610
283 + 8620327 = 8620610
379 + 8620231 = 8620610
421 + 8620189 = 8620610

Showing the first eight; more decompositions exist.
