Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684634, here are decompositions:

5 + 8684629 = 8684634
37 + 8684597 = 8684634
47 + 8684587 = 8684634
61 + 8684573 = 8684634
97 + 8684537 = 8684634
113 + 8684521 = 8684634
131 + 8684503 = 8684634
151 + 8684483 = 8684634

Showing the first eight; more decompositions exist.
