Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688488, here are decompositions:

19 + 8688469 = 8688488
79 + 8688409 = 8688488
139 + 8688349 = 8688488
229 + 8688259 = 8688488
331 + 8688157 = 8688488
379 + 8688109 = 8688488
421 + 8688067 = 8688488
577 + 8687911 = 8688488

Showing the first eight; more decompositions exist.
