Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678554, here are decompositions:

47 + 8678507 = 8678554
107 + 8678447 = 8678554
191 + 8678363 = 8678554
317 + 8678237 = 8678554
461 + 8678093 = 8678554
491 + 8678063 = 8678554
503 + 8678051 = 8678554
587 + 8677967 = 8678554

Showing the first eight; more decompositions exist.
