Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677420, here are decompositions:

23 + 8677397 = 8677420
29 + 8677391 = 8677420
53 + 8677367 = 8677420
131 + 8677289 = 8677420
137 + 8677283 = 8677420
173 + 8677247 = 8677420
197 + 8677223 = 8677420
239 + 8677181 = 8677420

Showing the first eight; more decompositions exist.
