Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679620, here are decompositions:

3 + 8679617 = 8679620
13 + 8679607 = 8679620
163 + 8679457 = 8679620
193 + 8679427 = 8679620
223 + 8679397 = 8679620
241 + 8679379 = 8679620
331 + 8679289 = 8679620
349 + 8679271 = 8679620

Showing the first eight; more decompositions exist.
