Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688404, here are decompositions:

7 + 8688397 = 8688404
271 + 8688133 = 8688404
337 + 8688067 = 8688404
421 + 8687983 = 8688404
523 + 8687881 = 8688404
577 + 8687827 = 8688404
607 + 8687797 = 8688404
691 + 8687713 = 8688404

Showing the first eight; more decompositions exist.
