Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662420, here are decompositions:

23 + 8662397 = 8662420
71 + 8662349 = 8662420
83 + 8662337 = 8662420
101 + 8662319 = 8662420
197 + 8662223 = 8662420
233 + 8662187 = 8662420
251 + 8662169 = 8662420
269 + 8662151 = 8662420

Showing the first eight; more decompositions exist.
