Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678620, here are decompositions:

17 + 8678603 = 8678620
101 + 8678519 = 8678620
113 + 8678507 = 8678620
173 + 8678447 = 8678620
227 + 8678393 = 8678620
257 + 8678363 = 8678620
281 + 8678339 = 8678620
383 + 8678237 = 8678620

Showing the first eight; more decompositions exist.
