Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644610, here are decompositions:

3 + 8644607 = 8644610
103 + 8644507 = 8644610
109 + 8644501 = 8644610
157 + 8644453 = 8644610
283 + 8644327 = 8644610
349 + 8644261 = 8644610
367 + 8644243 = 8644610
379 + 8644231 = 8644610

Showing the first eight; more decompositions exist.
