Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658426, here are decompositions:

13 + 8658413 = 8658426
43 + 8658383 = 8658426
97 + 8658329 = 8658426
103 + 8658323 = 8658426
113 + 8658313 = 8658426
137 + 8658289 = 8658426
149 + 8658277 = 8658426
193 + 8658233 = 8658426

Showing the first eight; more decompositions exist.
