Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684558, here are decompositions:

37 + 8684521 = 8684558
79 + 8684479 = 8684558
97 + 8684461 = 8684558
139 + 8684419 = 8684558
151 + 8684407 = 8684558
199 + 8684359 = 8684558
229 + 8684329 = 8684558
661 + 8683897 = 8684558

Showing the first eight; more decompositions exist.
