Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688626, here are decompositions:

13 + 8688613 = 8688626
19 + 8688607 = 8688626
43 + 8688583 = 8688626
73 + 8688553 = 8688626
157 + 8688469 = 8688626
229 + 8688397 = 8688626
277 + 8688349 = 8688626
367 + 8688259 = 8688626

Showing the first eight; more decompositions exist.
