Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679420, here are decompositions:

23 + 8679397 = 8679420
41 + 8679379 = 8679420
47 + 8679373 = 8679420
67 + 8679353 = 8679420
73 + 8679347 = 8679420
109 + 8679311 = 8679420
131 + 8679289 = 8679420
149 + 8679271 = 8679420

Showing the first eight; more decompositions exist.
