Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635420, here are decompositions:

11 + 8635409 = 8635420
107 + 8635313 = 8635420
137 + 8635283 = 8635420
179 + 8635241 = 8635420
257 + 8635163 = 8635420
347 + 8635073 = 8635420
359 + 8635061 = 8635420
449 + 8634971 = 8635420

Showing the first eight; more decompositions exist.
