Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645370, here are decompositions:

11 + 8645359 = 8645370
17 + 8645353 = 8645370
29 + 8645341 = 8645370
43 + 8645327 = 8645370
89 + 8645281 = 8645370
101 + 8645269 = 8645370
103 + 8645267 = 8645370
109 + 8645261 = 8645370

Showing the first eight; more decompositions exist.
