Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654420, here are decompositions:

31 + 8654389 = 8654420
139 + 8654281 = 8654420
163 + 8654257 = 8654420
199 + 8654221 = 8654420
331 + 8654089 = 8654420
373 + 8654047 = 8654420
409 + 8654011 = 8654420
457 + 8653963 = 8654420

Showing the first eight; more decompositions exist.
