Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658684, here are decompositions:

5 + 8658679 = 8658684
7 + 8658677 = 8658684
11 + 8658673 = 8658684
31 + 8658653 = 8658684
71 + 8658613 = 8658684
101 + 8658583 = 8658684
103 + 8658581 = 8658684
107 + 8658577 = 8658684

Showing the first eight; more decompositions exist.
