Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658722, here are decompositions:

13 + 8658709 = 8658722
43 + 8658679 = 8658722
103 + 8658619 = 8658722
109 + 8658613 = 8658722
139 + 8658583 = 8658722
151 + 8658571 = 8658722
229 + 8658493 = 8658722
409 + 8658313 = 8658722

Showing the first eight; more decompositions exist.
