Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640610, here are decompositions:

23 + 8640587 = 8640610
107 + 8640503 = 8640610
191 + 8640419 = 8640610
281 + 8640329 = 8640610
347 + 8640263 = 8640610
359 + 8640251 = 8640610
389 + 8640221 = 8640610
449 + 8640161 = 8640610

Showing the first eight; more decompositions exist.
