Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608420, here are decompositions:

47 + 8608373 = 8608420
173 + 8608247 = 8608420
179 + 8608241 = 8608420
257 + 8608163 = 8608420
383 + 8608037 = 8608420
449 + 8607971 = 8608420
503 + 8607917 = 8608420
599 + 8607821 = 8608420

Showing the first eight; more decompositions exist.
