Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658626, here are decompositions:

7 + 8658619 = 8658626
13 + 8658613 = 8658626
37 + 8658589 = 8658626
43 + 8658583 = 8658626
73 + 8658553 = 8658626
157 + 8658469 = 8658626
313 + 8658313 = 8658626
337 + 8658289 = 8658626

Showing the first eight; more decompositions exist.
