Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664420, here are decompositions:

7 + 8664413 = 8664420
31 + 8664389 = 8664420
43 + 8664377 = 8664420
53 + 8664367 = 8664420
103 + 8664317 = 8664420
109 + 8664311 = 8664420
197 + 8664223 = 8664420
227 + 8664193 = 8664420

Showing the first eight; more decompositions exist.
