Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688668, here are decompositions:

61 + 8688607 = 8688668
67 + 8688601 = 8688668
97 + 8688571 = 8688668
199 + 8688469 = 8688668
271 + 8688397 = 8688668
397 + 8688271 = 8688668
409 + 8688259 = 8688668
601 + 8688067 = 8688668

Showing the first eight; more decompositions exist.
