Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664620, here are decompositions:

7 + 8664613 = 8664620
61 + 8664559 = 8664620
67 + 8664553 = 8664620
73 + 8664547 = 8664620
103 + 8664517 = 8664620
193 + 8664427 = 8664620
199 + 8664421 = 8664620
397 + 8664223 = 8664620

Showing the first eight; more decompositions exist.
