Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641610, here are decompositions:

7 + 8641603 = 8641610
67 + 8641543 = 8641610
97 + 8641513 = 8641610
139 + 8641471 = 8641610
157 + 8641453 = 8641610
181 + 8641429 = 8641610
283 + 8641327 = 8641610
337 + 8641273 = 8641610

Showing the first eight; more decompositions exist.
